EPC is effective pip count.

The effective pipcount does not correspond to a CPW.

I get:

(jth) show onechequer
Number of rolls to bear off, assuming each player has one chequer only.
                       Pips     Avg. rolls   Std.dev.
gnubg                    43       5.842         1.197
jth                      38       5.230         1.123
Estimated cubeless gwc:  75.4465%


Effective pip count:
                       EPC      Wastage
gnubg                   47.712    4.712
jth                     42.712    4.712

EPC = Avg. rolls * 8.167
Wastage = EPC - Pips


That is, the estimated cubeless gwc is 75.4465%.
