Thanks, Neil, for the "+46 rollout result. Here is data for opening 21:

[$ S8] ~80
[$ S19] /92
[$ S5] <82
[$ S3] ^57
[$ S8] "+46

Key: $ = Slot (13/11 6/5), S = Split (13/11 24/23). Margins are in thousandths. After brackets is a bot symbol (~ Snowie, / GnuBG, < XG1 3-ply, ^ XG1 4-ply, "+ XG2 Roller+).

Adjusting for misreplies, GnuBG's $/S margin of 19 should be narrowed to 14 (based on David Rockwell's research), and XG 3-ply's and 4-ply's results narrowed (slightly, at most) from 5 and 3, to 4 and 2 respectively (based on Xavier's research). Snowie makes no misreplies, and XG2 Roller+'s are negligible.
