21$-62

Thanks to Tommy for his rollouts in this thread. Here is updated data for 21$-62 (money, dmp, save, go):

[S Z10 N19 $22 D22 R13 U31 W72] ~56*****20 5
[Z S2 N3 $19 D27 R30] /46**5
[S Z10 N12 $21 D26 R28 U43] <62**31
[S Z9 N15 D20] ^19*7 5

d[S N9 Z10] /10
d[S N7 Z11 D17 U18 R18 $20] <31*25 15**10 (David, new)
d[S N7 Z14 R18 U23] "<=10 (Tommy, new)

s[Z S13] /10 (where is N and $?)
s[N Z2 $10 S13 D15 R22] "<=46*9 (Tommy, new)

g[D N1 Z6 $13 S14] /5
g[N D9 Z18 S18 $20] "<=17 (Tommy, new)

Key: S = Split (24/18 13/11), Z = reverse split (24/22 13/7), N = Near (13/7 6/4), $ = Slot (13/5), D = Down (13/11 13/7), R = Run (24/16), U = Up (24/22 24/18). Margins are in thousandths.

Before brackets, d = dmp, s = save, g = go; else assume money. After brackets is a bot symbol (~ Snowie, / GnuBG, < XG 3-ply, "<= XG2 3-ply with XGRoller cube, ^ XG 4-ply) and the number of trials in thousands, rounded down (an asterisk is a repeater; not necessary after the final number).

For example, g[N D9 Z18 S18 $20] "<=17 means that at (gammon) go, N is best, D is -.009, Z is -.018, S is -.018 and $ is -.020 in an XG2 3-ply rollout with XGRoller cube of 17000+ trials. Note that this result overturns the Gnu rollout result of g[D N1...].
