Spider Solitaire Update

I continue to waste time playing Spider Solitaire winning 45 out of 100 of the second hundred games I played.  This is up from 37 wins for my first hundred games and brings my overall win rate to 41%.  This is consistent with random fluctuation but I believe I am getting better and that my expected win rate is now at least 40%.  It would not surprise me if the expected win rate with perfect play is 50% or better.
