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.

The way gnubg calculates the "Error based abs. FIBS rating" gives cube blunders a much lower impact. This was based on tests by Kees van den Doel.
