The Altitudes quoted in your POH are altitudes in the standard atmosphere. That means the height is referenced to 29.92 / 1013.2
If your altimeter was not set to 29.92 than the altitude you are flying at may not be the same as the altitude in the POH.
From a practical sense, unless you are flying with 29.92 on the altimeter, you have to make allowance for the difference between the Altimeter setting you are using and 29.92 to see how far you are away from the level you planned for.
What was the Altimeter setting you used and the OAT if you can remember?
