How is EV calculated?

[Lonneman]

For non-allin hands:
Is EV calculated street by street or just at the showdown?

For allin hands:
Is EV calculated street by street or only the moment I am allin?

Example:
Hero raises preflop.
Hero bets/calls Flop.
Hero is allin Turn.

In this example, let's say Hero is ahead on the Flop (+EV), but behind on the Turn (-EV).

Does HM take the Flop into account or does it just consider the street where the allin occurs - the turn in this example?

EV-calculation would be very inaccurate and quite useless if HM would not include the Flop in its EV calculation for the hand.

Hi, EV is calculated only for all-in hands and only considers the pot size and equity when the hand went all-in. It is a measure of luck after the hands get all-in which definitely is not useless.
