That makes my guess look pretty good, thanks! 🙂
One thing that those stats can be used to evaluate is the Clint Ballard BAP scoring system, and whether it's more or less fair than traditional scoring. For people not familiar with his scoring idea, it is:
Black Wins: 3 points
White Wins: 2 points
Black Draws: 1 point
White Draw: 0 points
This system is designed to promote decisive results, but also gives black an added edge in scoring because of the disadvantage he starts with.
Under the normal 1/.5/0 scoring system, using the numbers provided, it's pretty easy to see white's expected score:
(1*.37) + (.5*.35)
(.37) + (.175) = .545
So assuming equally skilled players, white expects to score .545 points each game, and black .455 (or 54.5% and 45.5% in the long run). As a ratio, being white is "worth" 1.2 times as much as being black.
In BAP scoring, white would have scored:
(2*.37) = .74 points per game, while black scores:
(3*.28) + (1*.35)
.84 + .35 = 1.19 points per game.
As a ratio, being black in this system is worth 1.61 as much as being white. Dropping the number of draws and redistributing them as wins among the two players (which is what the system is designed to do) does cut the gap down a little, but the system does still seem to sacrifice fairness in the name of excitement.
