Braulio Estima Statistics

It’s Science is back feat. the controversial Braulio Estima. To read this full artcle be sure to pick up of the upcoming issue of Jiu Jitsu Style Magazine. Here’s a taste along with some of the raw data.

—-

Notable Study Stats:

  • 60% of passes were from spider guard or X-guard
  • 93% win percentage
  • Scored first in 13 out of 14 winning matches
  • Submitted his opponent in 50% of wins
  • Highest sweep total in any study ever conducted* (“23”; *15 matches or less) – 1.53 sweeps per match average
  • His average match length was 7 minutes and 48 seconds
  • 71% of his submissions were chokes from the back
  • Had a 23/7 “sweep/pass ratio”

Abstract: All matches observed of Braulio Estima, used in this small sample occurred at IBJJF events, inside his weight division, and in the years 2011-2014. Only techniques, occurrences, and outcomes that were recorded are displayed in the data below (i.e. if no butterfly sweeps occurred, there will not be a representation of that in the sample data charts). Matches were selected at random based on freely available matches. This is a limited sample – but given the estimated amount of matches in this time period – it is well above the percentage necessary to create a scientifically validated trend sampling.
The Breakdown: There may not currently be a more controversial figure in competition jiu jitsu than, Braulio Estima. The multi-time world champion recently tested positive for DMAA, a banned substance; according to the World Anti-Doping Association, and has since been catapulted to the center of many discussions regarding jiu jitsu competition reform. It’s appropriate that someone like Estima is embroiled in this type of controversy; as he should be well recognized as one of today’s most accomplished competitors. Known for stunning technique and a sporty showmanship, Estima has a style that is completely his own.
While Estima’s style is unique, you will ultimately see some patterns in his game just like most of our other subjects. The primary difference in this is the variation in which he executes specific techniques. We recorded more positional variation in Estima than in any past studies of other competitors.
Estima had a 93% win percentage in our sample. Additionally, he scored first in 13 of 14 of those wins. He also recorded a high-mark for total sweeps among studies we have conducted of 15 matches or less (23 total). That’s an average of 1.53 sweeps per match. The highest we’ve ever recorded. You see this occurrence a lot with Braulio because he pushes the action. He’ll take an unstable sweep, come to the top position to capitalize – and with noting to take advantage of – ultimately concede the bottom position again to try his hand again.
There is a lot of spider guard and X-guard sprinkled into Estima’s notorious guard game. Approximately 60% of his sweeps and attacks came from a spider or X-guard variation. And while there are a lot of moving parts to Braulio’s bottom game, his top game is slightly less complex; something we’ve seen often among top competitors. Braulio prefers a heavy and compact style of passing; favoring a knee over or double-unders style of pass nearly 71% of the time. He recorded a measly 7 passes in the sample; however it’s important to note that Braulio beautifully uses the guard pass as an immediate transition to his opponents back. It’s common to see him use a double-unders pass to secure his opponents back.

It's Science: Royler Gracie (Legends Edition)

royler its science


 By: Tyler Bishop
(stats located below)

Foreword:

Thank you for making It’s Science one of the most popular jiu jitsu pieces on the internet and inside our little community. As many of you may already know, the full length articles, stats, etc. of all our competitor profiles are featured in every issue of Jiu Jitsu Style Magazine. This particular one will be released in the upcoming issue of JJS next month.
This particular episode kicks off our new series of statistical breakdowns featuring legends of the sport. Hopefully this new series can help us further paint a picture as to how jiu jitsu is evolving, by taking a closer look at where is has come from – competitively of course. I found no place more fitting to start than with the Gracie families most decorated sport jiu jitsu competitor, Master Royler Gracie.
This piece was of particular interest to me, as I viewed Royler’s style – from the outside to be different from many modern competition approaches, and I thought that an analysis of his game would prove to be a stark contrast to many past studies. I was both right and wrong. While his game does differ from many of past profiles, the results that he achieved were surprising in light of the results. His ability to play the top and achieve success is primarily where my attention goes in this breakdown, but I don’t think we should stop at that. Royler’s game is as clearly defined as any of the others we have observed in times past. I hope you will enjoy observing the results as much as I did collecting them.


Abstract:

All matches observed of Royler Gracie used in this small sample occurred in his respective weight division between 1994 and the present day. The sampling includes a mixture of both gi and nogi competition. Only techniques, occurrences, and outcomes that were recorded are displayed in the data below (i.e. if no butterfly sweeps occurred, there will not be a representation of that in the sample data). Matches were selected at random based on available matches – selected using a random generator from available matches. This is a limited sample, and one without many of our normal controls such as; unified rules, time limits, etc. This makes the data a little more skewed than what we would normally like to see. However, the data collected did end up accurately representing insightful trends that we can use to draw logical and rational conclusions. As jiu jitsu grows, so does that data.


Breakdown:

Royler Gracie, his name alone bears a connection to the sport itself. As the most decorated sport jiu jitsu competitor of Helio Gracie, Royler, is known for his flexibility, mysterious pressure, and fierce competitiveness. In fact, Royler recently competed once again at the age of 48 against Eddie Bravo in a thrilling match at Metamoris. It’s hard to deny the strong competitive will Royler possess. In fact, the famous picture above almost encapsulates Roylers mystique in-of-it-self. But, what techniques, strategies, and gameplans makeup the Royler Gracie style?
Let’s begin our review of the statistics below with a breakdown of the start of the match. Royler, like many of his generation, proved to be primarily a top game player. He displays a dynamic and smothering style of passing that he has leaned on heavily throughout his career, and the best way to execute that strategy is to start on top from the start. Roylers initial takedown of choice was the ankle pick and a wrestling style double or single leg attempt. It’s fair to mention that because many of these matches occurred in ADCC that many of these takedowns could have been specifically tailored to that format, thus giving them higher incidence than if this study was of only gi competition. These techniques accounted for approximately 78% of all of his initial takedowns.
Another strategy often used to arrive at the top position was a basic sacrifice throw in which he would drop his opponent down quickly into a butterfly style sweep in an attempt to gain the top position. Even if the throw did not work initially, Royler’s butterfly guard proved to be one of his “go to” assets on bottom. His flexibility, combined with his mastery of the technique, allowed him to secure quite a few sweeps from this position. In fact, nearly 42% of the sweeps we observed in the study were from butterfly guard. The nest most common position that he would sweep from was a simple collar sleeve open guard variation (best way to define it) – in which Royler would use butterfly hooks and scissor style sweeps to overtake his opponent. This style of play accounted for approximately 25% of his sweeping positions.
Once on top, there is a reason why many in the jiu jitsu community still refer to the knee through style of pass as the Royler Pass. Of all the competitors we studied, none averaged a higher pass rate than Royler Gracie. Royler passed the guard on average 1.6 times per match. Our next closest competitor was Gui Mendes with 0.78. Royler passed the guard more than twice as much as many of the modern competitors we have recently studied.
Royler’s guard pass of choice was  his signature knee through (or knee cut) style pass. 11 of the 24 guard passes we observed in the entire study were classified in this style (45.8%). However, Royler also utilized leg drag, torrendo, and reverse sitting half guard style passes with a high degree of success as well. Royler executed the majority of these passing sequences from his knees or from the half guard – which is very much juxtaposition from where we have seen it with the majority of the other competitors we have studied. In fact, no other competitor had the majority of their passes start from a kneeling position.
Royler recorded 88% of the submissions we observed from either the back or mount position. 50% of the submissions were chokes from the back while armbars and collar chokes made up the rest. 53% of the matches we observed ended with Royler finishing his opponent by submission.
In the matches we observed he was victorious in 13 of them. He has shown the type of spirit throughout the course of his career that you would expect from a decorated legend like himself. However, the numbers do reveal something very interesting. The dynamics of his style are unique qualities that – in many cases – we have yet to see replicated by any other competitor. In his last match against Eddie Bravo you could still see architecture of his proprietary game. And, while it’s likely we have seen the last of Royler Gracie in the competitive jiu jitsu world, it’s likely there is still a lot we can learn from the matches and legacy he has left behind. This is only a start.


Notable Stats

  • Highest average pass rate per match of any competitor studied so far (1.6 per match)
    • Passed the guard twice as much as the next closest in this category (Gui Mendes)
  • 88% of submissions came from the back or mount
  • Knee through style of pass was used to pass in 46.8% of successful attempts
  • 1/2 of total submissions he secured were chokes from the back
  • Scored first points (when applicable) in every single victory
  • 45% successful passes started from opponents half guard

It's Science: Guilherme Mendes

[youtube http://www.youtube.com/watch?v=5ZtTRrBPDOA?rel=0&w=560&h=315]
Welcome to another episode of “It’s Science”. We  continue our 2013 season with a quick look at Guilherme Mendes (2011-2013). Now on to the fun stuff…
Abstract: All matches observed of Guilherme Mendes used in this small sample occurred at IBJJF events, inside his weight division, and between 2011-2013. Only techniques, occurrences, and outcomes that were recorded are displayed in the data below (i.e. if no butterfly sweeps occurred, there will not be a representation of that in the sample data). Matches were selected at random based on available matches  – selected using a random generator from 18 total available IBJJF matches matches between 2011-2013. This is a limited sample – but given the estimated amount of matches in this time period – it is well above the percentage necessary to create a scientifically validated trend sampling.
So what did we learn?: Guilherme Mendes is an impressive competitor. Much like his brother, he is quite good at avoiding defeat. Inside this study – which took place between 2011 and 2013  – there was only one loss on his record. The best way to describe his style is, “insistent”. He insisted upon a handful of techniques, and was able to put himself in the exact position to execute these moves with absolute precision. Approximately 81% of his passes were executed in a very similar fashion – Half-Guard, knee slide, and nearly 88% of his sweep came from a  De La Riva to berimbolo-style of attack. His game was very effective. It saw him finish almost 60% of his matches by submission, and it him in position to be the first to score in 100% of the matches in that he was the victor. In observing his style and performance, I believe this is a very important metric for Guilherme. By being the first to score in his matches, he immediately put his opponent on defense, and was able to stay ahead and inside his own comfort zone. In his sole loss he did not score first, and was unable to build his normal momentum through out the match.
There is a lot that the average competitor can learn from Guilherme Mendes style and approach. While the techniques are far from “simple”, his approach and execution is very basic. He kept his attacks to a handful of techniques, and insisted upon them from the beginning. One thing to learn from his competitive approach, is that by building a match around your strengths from the start, you can put yourself in a consistently offensive game. This can help reduce hesitation and can ensure that techniques are executed properly under pressure.

Notable Stats:

    • 7:15 was his average match length
    • Won 58% of his matches by submission
    • Scored first in 100% of his wins (91% total)
    • Passed from the half-guard 81.5% of the time
    • 88% of sweeps occured from the De La Riva guard
    • He preferred knee-cut passes to leg drag passes 13/2
    • Approximately 77% of his submissions were from the side control position
    • When on the feet he preferred pulling guard – as he did so 85% of the time

Romulo Barral Jiu Jitsu Stats, Info, & Matches

[youtube http://www.youtube.com/watch?v=HGPvcT0NjNA&w=560&h=315]

Romulo Barral Breakdown

Welcome to our second season of “It’s Science”. We are going to kick off  with a quick look at Romulo Barral. The recently “retired” Barral is one of the most accomplished competitors of all time. Let’s dive deep into what makes him so successful.

Abstract of Romulo Barral Jiu Jitsu Study:

All matches observed of Romulo Barral, used in this small sample, occurred at IBJJF events, in his weight division, and between 2011-2013. Only techniques, occurrences and outcomes that were recorded are displayed in the data below (i.e. if no butterfly sweeps occurred, there will not be a representation of that in the sample data). Matches were selected at random based on available matches via YouTube – selected using a random generator from 20 total available IBJJF matches between 2011-2013. This is a limited sample – but given the estimated amount of matches in this time period – it is well above the percentage necessary to create a scientifically validated trend sampling.

So what did we learn?

Romulo Barral has a very defined game. My initial impressions of him were in many cases correct, but there were a few surprises. You will immediately notice in the 13 total matches observed that Romulo Barral limits his arsenal to just a few defined techniques. I have always perceived him as a spider guard player – and perhaps that is true – but one thing that is overwhelmingly obvious is how this game has evolved into a sit-up guard style system from the bottom.
In fact, 70% of Romulo’s sweeps came from the sit-up guard position. From there his passing style of choice is a very heavy half guard style of passing with 66% of his passes coming from half-guard. It was also very obvious that Barral’s end-game involved the mount.
All but one submission occurred from the mount position. So is this style of game successful? In short, yes! In the random matches we observed, he won 12 out of the 13. That’s pretty good.

Notable Stats:

  • Sit-up guard accounts for 70% of sweeps
  • Half guard passes account for 2/3 of all passes
  • 4/5 submissions were cross collar chokes from the top
  • 4/5 submission also occurred from mount
  • Barral scored first in 10/13 matches, and 10/12 that he won
  • His average match length was 7.23 minutes
  • He pulled open guard in over 50% of his matches
