There is a lot of misunderstanding about what "EV" is, unfortunately it is not really a measurement of luck, it is a measurement of Expectation - which is vastly different from luck. PokerTracker 4 attempts to correct this misunderstanding by no longer using the term EV at all, because true EV is a measurement of any action vs an opponent's range, EV is not supposed to be all-in vs another specific hand after the action took place. In true EV calculation the opponent's range includes hands that would call and lose, hands that would fold, and hands that would call and win (sometimes there are no hands that would call and lose or call and win but thats not important to this example). Instead of All-In EV, we use the term All-In Equity. Thats a lot more logical, because what we are really doing is taking two or more hands and comparing their equity, then multiplying the equity by the size of the pot.
PokerTracker 4's All-In Equity calculation is the most advanced we have seen to date, we account for ties and use full enumeration while calculating the equity in multiway pots, in headsup pots we use a very accurate montecarlo lookup table to save time. We start the calculation from the point where there are no further betting actions to take in the pot, in the event of multiway pots we disqualify any hands where a player's hand is unknown if they in fact had equity in the pot; this is because we cannot calculate that player's equity, mathematically it would be wrong to assign that player a 100% hand range. Admittedly this results in a slightly positive bias, but it is much better than a negative bias that would occur if we assigned random hands in multiway pots and did not disqualify these hands. For optimal results, all-in equity adjusted winnings should only be calculated in headsup games, but we understand that is not what the users would want - so we give this disclaimer that a bias will be unavoidable in multiway pots where one player's equity is undetermined.
If you play tournaments then you should also look at Net Adjusted Winnings, this is ICM-converted Equity Adjusted Winnings in your currency, rather than in chips. This stat shows how your actions at a final table show your net expectation of the prize pool - once again this is not a measurement of luck, its a measurement of expectation.
When choosing a software application to automate your All-In Equity (or all-in ev in other applications) be sure to ask the developers what their calculation methods are, you will find that others differ from this description - you should know what the differences are and how it affects your results.
