In this post, I listed some money and gammon save data for positions in which splitting and hitting on the 2pt or 1pt with X is an option.

I'm adding to that by posting a GnuBG rollout below. It was sent to me with only the S and U plays (currently in second and third place). I added X, D and Z. The result now closely agrees with David's XG 3-ply rollout of s[X S4 U7 Z17 D25] <31**20 15.
