Notable Info

• Code update to 1.16.  Expanded on prediction-based launching.  Assisted the elevation of fighters who continually and decisively beat higher-rated fighters without quantifiable weakness in outcome.  This is a relatively minor change.
• Matt Serra and Ricardo Arona will have been inactive for more than one calendar year, and will be dropped from the rankings until they have another bout.
• Addition of a few minor shows.

Notable Info

• Ratings include effects from recent EliteXC, GCM Cage Force, Fatal Femmes, IFL, and other minor shows.

The next planned update is on Sunday, April 13.  However, there may be an intermediate release in the middle of the upcoming week if I decide to release a prediction-based code change that I am testing.

Notable Information

• Changes from recent UFC, KHAN, HEAT, and other shows.

Kenny Florian moves into the Lightweight Top 10, while Thiago Alves blasts his way into the Welterweight Top 5!  Check out all of the divisions to see the various changes caused by these recent shows.

The next update will be on Sunday, which will display the effects from the FatalFemmes and EliteXC shows, as well as others.

Notable Information

• Code updated to 1.15b.  Re-worked technical decision outcome consideration. Fixed bug in draws which could occur in fights w/ huge gap in points.  Reduced extreme upset protection, relying more on past results then prediction.
• Effects from shows in past week, as well as old shows recently added.

Rankings have been updated on March 27, 2008

Notable Info

• Rating code updated from 1.13c to 1.14b.  Changes related to situations in which fighters come back from inactivity.  Especially those who have had good performances in their 1st and 2nd bouts back.  This has caused moderate reshuffling throughout the divisions, but leaves the top 25s relatively untouched.
• Shows from the past week (WEC, Pancrase), as well as old bouts have been added to the database.

Expect the next update to come on Sunday.

Information

• WEC 33 results, as well as recently added bouts.
• Updated basic code for properly placing fighters coming back from inactivity.  This will cause minor effects throughout the divisions, especially for those who had recent instances of inactivity, as well as their recent opponents.

Rankings posted.  Data from March 23, 2008.

Notable Changes

• Ratings code updated to 1.13c. GTR modification, support for technical decisions/draws (rare), code cleanup.
• Rankings expanded to Top 100 for Lightweight through Heavyweight.
• Rankings expanded to Top 50 for Bantamweight, Featherweight, and Women’s.
• Rankings expanded to Top 25 for Flyweight.
• Fighter names are now hyper-linked and directed to the fighter’s Sherdog profile.
• Approximately 250 bouts added since last update for shows in March 2008.
• Approximately 160 bouts added since last update for shows prior to March 2008.

Now that the weight classes are expanded so far in the thinnest divisions (Women, Bantam, Fly), it is almost a certainty that we are mistakenly excluding fighters toward the bottom of the lists due to lack of division assignment.  If you feel there is a fighter that should be in one of the lists, please feel free to ask us for their current division assignment for verification.

Its a slow week… but we will be releasing an update on Sunday.

Expected Changes

• Expanding Lightweight through Heavyweight to Top 100.  There should be expansions for the smaller divisions as well.
• Fighter names will now be hyper-linked to their Sherdog profiles.
• Code updated to v1.13.  Only change is an update to the GTR initiative mentioned in the previous post.  The effects will be minor and limited to the lowest weight divisions.
• Approximately 250 old bouts added to the database.
• A few minor recent shows added to the database.

As you may or may not know, the PRIDE and UFC titles have been acknowledged by our rating system and have been given precedence, or “double verification” that a fighter has been a top fighter in a top brand of MMA.  We hand selected those organizations due to the quality title defenses, quality of reigns, and overall quality of fighters in general.  Its really a combination of a half dozen things.

Those participating in these title contests get very small boosts proportional to their performances, and extended exemptions from quality performance decays.  The downside to this is when they are no longer participating on the title level, they are subject to falling down the ranks more quickly.

Through my experiences in computerized rating/ranking systems, I have noticed that when there are different brands with sometimes vast, yet unquantifiable differences in talent pools, there needs to be a method for planting an artificial seed or subjective variable to represent that “little extra” to show that the lineage, prestige, and other intangibles that exist in the dominant brands.  Furthermore, this also acts as a defense against the smaller organizations pooling points within their fighters, hence the start of the GTR initiative.

After looking at the global MMA scene, its really split into two distinct markets where fighters don’t crossover THAT much.  Those two markets are Asia, and Europe/North America.  Our goal is to have a quality title, for each weight division in each market, at any given time.  If none exists, it will simply be vacant.  Currently, the GTR provisions are acknowledged for the following titles:

Fly – Euro/N.America: Vacant / Asia: Shooto

Bantam – Euro/N.America: WEC / Asia: Shooto

Feather – Euro/N.America: WEC / Asia: Shooto

Light through Heavy – Euro/N.America: UFC / Asia: Vacant (was PRIDE)

The effects of the GTR will be seen in the next update, but will only cause mild changes in the lower weight divisions.

MMA rankings have been updated to include results from this weekend’s DREAM & Icon events.

We also decided to make the Division Dominance List a permanent part of FightMatrix.com!  This list will be updated with every rankings release.

This tournament will without a doubt, reshape the Lightweight rankings.  The rankings below are current, with the latest code, which shouldn’t be much different than the live rankings.

Some of the fighters are matched much harder than others!  So much for seeding…

Lightweight GP

[#2] Gesias Calvancante vs. [#6] Shinya Aoki

[#10] Tatsuya Kawajiri vs. [#65] Kultar Gill

[#4] Mitsuhiro Ishida vs. [#225] Bu Kyung Jung

[#77] Kazuyuki Miyata vs. [NR] Luiz Firmino

[#31] Andre Amade vs. [#39] Eddie Alvarez – Projected LW ranking for Alvarez

[#50] Artur Oumakhanov vs. [#151] Katsuhiko Nagata

[#17] Joachim Hansen vs. [#34] Koutetsu Boku

Anyone know why there aren’t 8 bouts??

Ranking Note: Gray font represents an approximate ranking. An asterisk represents a fighter who is ranked, but too low for an approximation. These two scenarios will clear up slightly as we move forward. “NR” means the fighter is not ranked, due to inactivity, or due to a rating that is at or below the default starter rating.
