What is the problem?
The first number (-0.609) is normalised luck whereas the number in
parentheses is luck measured in match winning chance.
If you roll a -0.200 joker in the first game of a 3-point match it'll
give a luck rate of
equity -0.200
mwc -1.97%
If you roll a +0.100 joker in DMP this gives you a luck rate of
equity +0.100
mwc +5.00%
Your total luck rate is:
equity -0.100
mwc +3.03%
That is, a negative luck rate measured in equity and a positive one
measured in mwc.
In general, (player 0 skill + player 0 luck) - (player 1 skill + player
1 luck) should sum up to the result of the game; 100% if player 0 wins,
0% otherwise.

'user' has a automatic redouble as he is down 0-1 in a three point
match.
gnubg's take point is 30%. However, gnubg thinks that no sequence takes
'user' below 30%, so 'user' can double now or double on next roll.
Technically, it is a redouble, but since there is no market losers it
doesn't cost anything to wait.
