I agree with Stevie, i think it should be Zero to both.
for example, i draw 3 games in frogs, without having 25 games played and was a zero for both of players in the 3 games.
I don't think (and understand) why it is different now.
I know the bug but i posted here like i received.
Thanks to you both for the replies.

Hello, i draw a game with num1fire and the result was this:
Nuno Miguel: old BKR = 2106, new BKR = 2106 (0)
num1fire: old BKR = 2340, new BKR = 2301 (-39)

I think this is not right cause our rating gap was 234 points and should be add zero points to both of us.
thanks
