Poker players who are active in online forums often discuss the EV or Expected Value of a decision. Expected Value is a forward projection of winnings which incorporates the range of hands that your opponent may hold. At this time, software cannot accurately determine an opponents range of possible hands, therefore EV calculation could only be performed in scenarios where all players are effectively all-in; the terminology All-In EV was born from this adjustment.

With the advent of PokerTracker 4, we have moved away from using the terms "EV" and "All-in EV" because the terminology for these phrases are misleading, they do not truly represent Expected Value because these are results oriented stats rather than forward projecting stats. To replace All-In EV in PokerTracker 4, we have introduced a new concepts called "All-in Equity" and "All-In Equity Adjusted Winnings" which better represents the functionality of the stat while improving accuracy. This guide will discuss the differences between the terms, why the change was made, and how to interpret graphs which use these stats.
