Whole-History Ratings

The Whole-History rating system is a system designed to estimate the skill of players over time, it is loosely based on the Elo rating system.

This implementation of the Whole-History rating system contains one variable set to the following value;

  • w²: 33.0625 (w: 5.75)

The w² value is the maximum rating² per day that a fighter can change.

This rating system works by iterating over an entire set of results to work out the curve of skill level that a fighter changes over their career. Instead of working incrementally like Elo or TrueSkill, where each new result changes the involved fighter's ratings, Whole-History will update past ratings based on new information.

By working through both directions in time, it allows ratings to be adjusted retroactively based on future performances.

  • Fighter A, an established fighter, beats a new fighter, fighter B.
  • Since fighter B is not highly rated, fighter A's rating doesn't increase much.
  • Fighter B goes on to win his next few fights against high rated opponents.
  • Fighter B was therefore probably a lot better than his original rating would imply, so his original rating is increased to reflect that.
  • Since fighter B's original rating is now higher, the rating of fighter A will also increase as we now know with hindsight that his win should have been worth more.

By retroactively adjusting ratings, a more accurate set of skill ratings can be created over the course of a career. The skill rating after the last fight being the current rating.

The Whole-History rating system does not handle draws, this implementation treats a draw as a win and a loss on the same day against the same opponent.

These ratings exclude fighters who have not fought within the last 18 months.
