Yes.
gnubg error rate:
overall error rate
-----------------------------------------------
unforced moves + close or actual cube decisions
snowie error rate
overall error rate
-----------------------------------------------
total moves + total cube decisions
Opponent:
gnubg error rate : -3,658/(139+64) = -0.018
snowie error rate: -3,658/(152+160)= -0.0117
You
gnubg error rate : -2,907/(134+53) = -0.016
snowie error rate: -2.907/(148+88) = -0,0123
Your opponent had the cube ownership a lot with 160 cube decisions.
However, gnubg estimates than 100 of these were trivial (e.g.,
scrambling home to save a gammon or trailing a gazillion pips in the
race), so even though your opponent gave up more equity than you his
snowie error rate is still lower due to 100 trivial cube decisions.
