In Response To: win probability for a PR difference and match length (Rick Janowski)

I contacted person who invented revised-elo rating system for backgammon in the 80's for purposes of KG Rating List. He is chess master and mathematician. Found him via Facebook last year. He told me he published it 30y ago and does not remember much.

Danish modificiations are interesting to me, since it's counter-reasonable for me current FIBS rating points won/lost for SHORT matches. In FIBS system, you win more rating points if you beat somebody three 5pters then when you win ONE single 25pointer.
