Finding the PNL from ACCOUNT_UPDATE event

Hey People,
Is there any way to learn the PNL from the ACCOUNT_UPDATE event?
I know there is the unrealized_pnl attribute in the event, but it does not match the position PNL.

Is there any way to know the PNL based on the event?


Why do you say up (unrealized PNL) “does not match the position PNL”?
How did you test and with what variables?
