It does not appeal to the new way to me to calculate the BKR. the stronger players are a lot penalized and if 100-150 difference is one points forgiveness a lot rating. I nearly had arrived beyond the 2500 points in backgammon (modestly and with hard work against all) and in little time I have lost 160 points (watches my diagram).
Type can go well for chess or similars but absolutely not for the backgammon where the player with a rating of 1500 can strike one with 2600.
Therefore one stimulates the strong players not to play!!!
