This stat has been causing a lot of confusion. After a discussion we came to the conclusion that it’s best to have 0 be the breakeven point and add negative values. Every loss should return -1, currently it returns 0. Wins are correct.
An example: facing a pot sized bet (we’re getting 2:1 pot odds):
a) winning one hand and loosing one hand: 2-1=1
b) winning one hand and loosing two hands: 2-1-1=0
c) winning one hand and loosing three hands: 2-1-1-1=-1
Another example: facing a 2x pot bet (we’re getting 3:2 or 1.5:1 pot odds):
a) winning one hand and loosing one hand: 1.5-1=0.5
b) winning one hand and loosing two hands: 1.5-1-1=-0.5
c) winning one hand and loosing three hands: 1.5-1-1-1=-1.5
d) winning four hands and loosing six hands: (1.5*4) – (1*6)= 0
And another example: facing a half pot bet (we’re getting 3:1 pot odds):
a) winning one hand and loosing one hand: 3-1=2
b) winning one hand and loosing two hands: 3-1-1=-1
c) winning one hand and loosing three hands: 3-1-1-1=0
d) winning one hand and loosing four hands: 3-1-1-1-1=-1
Split pot hands currently return 0. They should return half the value it would have been if the pot had been won.
