Hi!
I saw an incorrect value for Equity Ac5c vs QcTc (preflop All-in in SnG FR on FTP) as 55.6% vs 44.4%. But in calc - 57.363% vs 42.437%.
In HM replayer also 58% vs 42%.
My HM version 1.11.06d. Update to 1.11.06g and load hands in new base not led to any changes Equity.

PS: sorry, in topic title instead "hand equity" I wrote"EV".

We had a EV bug 1.11.06 - 1.11.06d (fixed in 1.11.06e and also didn't occur in earlier versions)
If you ever imported hands into the affected versions, please update to the latest version - http://www.holdemmanager.com/Downloads/HmUpdate.exe
create a new database and reimport the hands.

we need the original handhistory to check this - you should find it in the archive folder (default c:\hmarchive).

Real equity in the hand is:
A5s: 57.0653%
QTs: 42.3399
splitpot: 0.5948
This is what's used for the ICM calculation (and for the cEV and $EV Diff calculation).
The replayer can't display the splitpot chance, so it will show:
56% vs 44%. (I'm surprised why it doesn't show 57% vs 43%, but I guess it rounds off the number differently)
The Equity column should also display 57%.
It displays 55.6%. Again, also because it doesn't understand what to do with the chance of a split pot.
---
If you look at another hand:
48o vs TJs (allin on the 82T flop)
You'll see it will correctly display the 22.9% Equity. (exactly the same as if you press the ICM button) The reason this is dead on accurate, is because the chance of a splitpot when you go allin on the flop in this hand is 0.00%.

Let's calculate backwards:
cEV Diff is 1962 chips.
Effective stack in the all-in hand is 1710.
1710 x 2 = 3420 total pot size
1962/3420 * 100% = so ~57.34% is what HolderManager uses? (NOT the 55.6%)
Where does the 57.34% and 1962 chips come from?
A5s: 57.0653%
QTs: 42.3399%
splitpot: 0.5948%
(57.0653%*3420)+(0.5948*1710)= (1951.63 + 10.17) = 1961.80
So 57.34 isn't used at all. It's the result of using 57.0653%, and the 0.5948% chance of a splitpot.
