### HELP! All-in Equity Value Difference Calculation

There are still some hands in which I just can't make Poker Copilot calculate the same all-in equity value as Hold'em Manager, with no idea why.

Can you see what I'm doing wrong here? I'd appreciate any feedback, so that I can get the formula right and meet my self-imposed Friday deadline.

Given that for the player stevoski111:

pot              = 545 cents
rake = 36 cents
amountWon = 509 cents
equityPercentage = 87.2% (and Hold'em Manager agrees)

I'm using this formula, which I thought was the formula used by Hold'em Manager:
All-in EV Diff = equityPercentage * (pot - rake) - amountWon
= 0.872 * (545 - 36) - 509
= - 65 cents

Hold'em Manager thinks the All-in EV Diff is -58 cents. Poker Copilot thinks the All-in EV Diff is -65 cents.

Here's the hand:

It looks correct... There might be some errors with HEM that are unexposed...

The formula you are using is correct. The difference there is indeed correct. :v/
