One more fancy graph.  WHR histories for all fighters who set all-time highest WHR records during their career.

In other words… fighters that (by WHR standards) were “the best fighters ever” at some point when they fought.  Josh Barnett is a bit of a surprise… otherwise, names we all expect.

Three guys whose careers have been associated with one another… If Jones/Miocic ever happens, it will all come full circle.

Notable Info

• After recent changes were made, extensive testing of the w2 value suggests value used in WHR be changed to 42 (from 10).  WHR ratings updated.

Notable Info

• It turns out the WHR system that we recently rolled out does not properly handle draws — for every draw, it was adding a win AND loss.  Since I lumped close decisions in with draws based on the research I did w/ the Glicko system, this caused a pretty large ratings issue.  I started noticing strange patterns of fighters in draws and close decisions who both lost considerable points directly after the fight.
  Further research is required to determine if this is a systemic problem or an implementation problem.  In the interim, I updated the WHR ratings and tossed out all draws, along with no contests and disqualifications.  Before, we were also treating split & majority decisions as draws in the WHR ratings, but we will now treat those as wins (for now).  Furthermore, I increased the accuracy as the ratings now run until the convergence is below 0.00001 (vs. 1.0).  Technically, this paints a more “accurate” picture.

Notable Info

• “WHR” (Whole History Rating) is now available within the current ranking pages.
  • • WHR is yet another mathematical system that is based on Elo, but is drastically different.  While the standard, Elo, and Glicko rating systems are executed once to produce ratings output, where ratings move incrementally after each bout, the WHR system depends on numerous iterations to build the current ratings.  In doing this, the system is able to use knowledge derived from previous iterations to build a supposedly more accurate picture as it can also use what fighters and their chain of opponents did before AND after their respective bouts.  You can read more about that system here -> https://www.remi-coulom.fr/WHR/.  There is also more info in the FAQ page.  Note: The actual WHR ratings have been increased by 1750 points as a display-level modification, so the rating point values match up better with Elo and Glicko for comparison purposes. WHR ratings as posted are likely to change in the coming days as we dig in to try and improve prediction rate.
• Glicko-1 ratings reduced by 500 points.  This is a display-level modification so the ratings match better with Elo (which start at 1000 instead of 1500) and WHR systems.
• For the new “Underrated” and “Overrated” designations, we’re moving over to an Olympic-type model by dropping the highest and lowest ranks of the 4 mathematical ranking systems, before making the calculation.
