yaps: igp

Poker players often talk about getting their money in good. Of course, you can only know if you got your money in good after the fact; the hand must go to showdown. If if doesn't go to showdown, you'll never know what holding(s) your opponent(s) had, so you'll never know if you got your money in good or not. It's been a while since I cooked up a poker statistic, so it's high time for a new one. Without further ado, let me introduce to you - for the first time on any stage - what I'm calling igp. It stands for in good percentage. Here's how it's calculated:

step 1: start with the hands where you went to showdown
step 2: cull out the hands which had a negligible delta; the remaining hands are the examination set
step 3: for each hand in the examination set, determine whether you got your money in good; my current definition of getting your money in good is when your probability of winning the hand at the time when you wagered the most money was greater than 50%
step 4: the igp is the ratio of the number of "in good" hands to the number of hands in the examination set, multiplied by 100

My guess is that though I came out with a net loss last night, my igp was well over 50. I'll have to write some tools soon to do these calculations, and find out whether I'm right or just blowing smoke :-)
