Yes, the system is rubbish. I just checked out a waiting game, and I stood to lose 83 if I lost the game, and get 1 point if I won. Why would I even bother? What encouragement is there for good players to play against novices.
And winning (or losing) by a gammon or backgammon should involve a premium. It's ridiculous that the same points are used when on wins by a backgammon, and when there is just one point difference at the end
