Here is data for 52D-54:

Money
Snowie .. [D R9 S20 $58] 20k 10kS 5k$
GnuBG .. [D R21 S24 $49] 5k (only)

Other scores (GnuBG)
d[R S3.7] 15kR 5kS
s[D R6.4 S31] 15k 5kS (new rollout, posted below)
-2-4 [R D2 S26] ^12k

Key: D = Down (13/9 13/8), R = Run (24/15), S = Split (24/20 13/8), $ = Slot (13/4). Error sizes are in thousandths.

Info just before the brackets denotes non-money score: d = dmp, s = (gammon) save, or -2-4 = needs 2 needs 4. After the brackets is the number of trials (in thousands, rounded down). For example, "s[D R6.4 S31] 15k 5kS" means that at (gammon) save D is best and R is -.0064 after 15000+ trials (and S is -.031 after 5000+ trials).

Neil, it may be worthwhile to add 52D-54 for money, DMP and GS to your XG 4-ply queue.
