In Response To: Find an ace - 2ply Rollout (Daniel Murphy)

I was interested in the 0-ply vs 2-ply issue. Still not enough trials to reach a definitive conclusion, but the results are surprisingly (I think) close:

1. Rollout bar/22 8/7 Eq.: -0,3929

0,4041 0,1054 0,0033 - 0,5959 0,1903 0,0064 CL -0,2798 CF -0,3929

[0,0026 0,0016 0,0003 - 0,0026 0,0022 0,0004 CL 0,0074 CF 0,0210]

Full cubeful rollout without var.redn.
