We’ve had a number of questions into support on what the TAP (true aggression percent) stat is, and how it’s calculated, so I wanted to address it here because it is a cool stat and it can be a very useful indicator for someone’s real post flop aggression.
So TAP% is this basic formula:
total bets + raises / total streets seen (postflop only)
checkraise = +2
bet raise = 1, except for flop cbet (if flop c-bet, then bet = 0)
So essentially it’s counting checkraises as twice as strong, and players who are the pre-flop raiser, and c-bet, those bets do not count. But if they are the pre-flop raiser and check, then that counts as a passive action. It’s removing the process of c-betting into the post flop aggression since people c-bet a decent amount of the time, and sometimes too much, but what we really want to know is how aggressive they are playing if they are not the pre-flop raiser, or if they are the pre-flop raiser, how they are playing on later streets. It’s eliminating the common situation, and putting more emphasis on the uncommon play that creates the biggest decisions for users post flop.
The main reason this stat was created was because AF, and AGG% alone can sometimes be watered into numbers that aren’t really accurate for most players if they raise a lot pre-flop, and c-bet, but don’t do much else. So then you’re left having to look at a lot of other stats to figure out where their aggression really is. This TAP% gives a quick over view of what kind of post flop player you’re against, and is better weighted and provides more information than stats like WWSF. All of these numbers are helpful, and TAP% is another stat that can be used in smaller sample sizes to make quicker reads.
