Gnubg’s hypothetical FIBS rating methodology should be amended to ignore “forced moves” from the calculation.   Many times, I have played terribly, but  because I have many forced moves, i.e. dancing on the bar, gnubg tells me I am an “Advanced”, or “Expert” player.

I may be incorrect, but it seems that gnubg is not currently ignoring forced moves.

There's always been a lot of discussion about how to assign ratings based on
checker and cube errors and particularly their ratio.
Some have commented that Gnubg is too harsh with it's ratings for cube errors.

Based on my GNU v SW money play series both Gnubg and S4 have a ratio in EMG where cube errors are ~35% the size of checker play errors.
(I took the liberty of removing a S4 beaver blunder in a highly unusual position to get this number).

Is there a way to use this as some kind of benchmark and incoprporate this into Gnubg's rating assignment?

Obviously there's Matchplay to consider as well.

I just wanted to start off a discussion.
