Sorry, I've lost track of this thread. Where is the error in the numbers

NO NO NO!
The values returned by getMatchPoints *must* be compared with a gwc,
i.e., arOutput[ OUTPUT_WIN ]!!!!
The numbers above say that pl0 can take a double when he has a game
winning chance of 21.450% - 26.413% depending on recube-vig. The numbers
do *not* say anything about the MWC he must have to take!!!
