In Response To: Variance Reduction (rambiz)
When talking about the confidence intervals reported by the bots, I think you need to distinguish between different bots. As I understand it, GNU operates a full dice rotation while XG only rotates the first roll over a 36 roll cycle. In addition, once an XG rollout reaches 72 trials there is always a sudden sharp closing of the reported confidence interval, caused by it calculating from that point on separately for each of the 21 initial rolls and then combining. I don't think GNU uses any such method and doubt its legitimacy. 6621D/P twice means zero variance for an initial 66?
