There was mentioned chess rating isnt good for backgammon. Chess rating is calculated after tournament. And winner (or whatever else w/ same ammount of points) cant lose his rating. Say, there is tournament where is playing player A w/ rating 2100 and thre other players w/ ratings around (B, C and D) 1900. Player A must earn 75% of points to save his rating. Say players ABC beat player D and rest of games are draw. Then player A has 2pts, so he is losing rating. But due to rule mentioned above he is losing nothing.
I suggest implement this rule to protect higher rated players.
