You can extract the info (stacksizes+sb+bb+ante+number of players) you need for Mzone and BB calculations from the last hand history I guess? So it should be possible to make this work with the HUD?
:|
MZone formula
M = (s/(sb+bb)+(a*p))
s = stack size
sb = small blind
bb = big blind
a = ante
p = number of players at your table
