Hi all, I've been away from this list for a while. Just
thought I'd post an update on ParlorBot's stats, after about
5 months in service running 0.13.0:
Number of samples : 15992
Lowest : 1856.69
Highest : 2154.10
Mean : 2005.42
Standard Deviation : 52.34
Again this is 2-ply play and cube decisions, "narrow" move
filters, 33% reduced.
Cheers,
-- Rod
