On the XG 'Opening Book' site, Slotting with an opening 41 in money play costs -.0153 . . . but when I consult my own XG2 software, the cost of slotting nearly evaporates at -.007. Could someone clarify the reason behind this discrepancy, and which source is considered more currently authoritative?
More significantly, I found myself more stiffly punished for slotting with 41 in match play, in the opening game of a 7-point match . . . and then discovered that I get 'book' values for slotting as a substantial -.039 error in match p[lay even in opening games of a 15-point match.
This is as much a question about how to interpret my various XG sources as it is about the opening 41 play. Why is this figure so substantially different in match play vs money play? And for money, is slotting essentially on a par with splitting, or is it a small but palpable error?
