Yes, this is correct.

Gammons and backgammons are absorbed into the various points (DP, CP,

No, they're are cubeless gwcs -- I guess this is the crusial point I
didn't emphasize earlier. So they should be compared to OUTPUT_WIN.

For gammonless moneygame:

Dead cube:

DP = 50%
CP = 75%
TG = 100%

Live cube:

DP = 80%
