OK - now I see why you said you'd considered removing those stats. But
my next question would be - should the stats for a cubeful rollout
actually reflect the wins/lose/gammons etc. including cube play?

I just googled and as I read it, he's suggesting branching at
double/takes, not continuing after double/pass.
