Ive just noticed a really odd thing when doing a filter. I filtered for B, X, XC vs a 55-80% river bet when I have 2nd pr or less. 9 instances come up, I only won one of them so 'River Call Win' is correct at 11% but river call efficiency is 1.62!!! The hand I won was a much bigger pot, is this why? I'm stumped as to why it would give such an inaccurate reading given I can usually trust it to be consistent (I know breakeven isn't 1 but is usually less). Ive attached an image to show the issue. Any help would be appreciated.
