# Pokertracker Ev

Hi, Just downloaded PT4 and im using it for heads up HTSNGs, I was just wondering how accurate the EV line is when looking at the graph of tournaments vs prizes. Because it seems that the prizes ev is different to the chip EV.

Don't really know how this works, any help appreciated.
Thanks

Before we begin, we must clarify that the line you are looking at is not EV. Players incorrectly discuss EV as it applies to trackers, according to the rules of mathematics the calculation of Expected Value requires a variable, which in the case of poker would be a hand range for an opponent. Of course a human being is needed to determine the opponent's hand range, a computer cannot perform this, therefore we instead created a new stat called Equity Adjusted Winnings. The definition is simple, take your equity when all-in with one or more streets to come vs your opponent's hand, then multiply the equity by the number of chips in the pot - so if there are T5,000 chips in the pot and you have 65% equity, your All-In Equity Adjusted Winnings are T3,250. This is a measurement of expectation, not luck or EV... so this does not tell us if you are running hot or cold, lucky or unlucky... it only tells us if you are running above or below expectation.

As you can see, even though that is not EV or luck measurements, it is still rather handy to know if your running above or below expectation - but that is only a measurement of chips. What about above or below expectation in tournament winnings? For this PokerTracker 4 incorporates ICM to determine the value of each chip at the final table of a tournament, and then multiplies the ICM value per chip times the chip expectation (you called this chip EV). We then subtract the ICM Adjusted Winnings from the ICM Adjusted Expectation to result in the Net Adjusted Winnings (before this post, you might have thought that this was All-In Tournament EV, but as shown before a tracker cannot really calculate Expected Value, it requires knowledge of an opponent's range).

Now that the above is out of the way, I can confirm that Net Adjusted Winnings is accurate for all HUSNGs that can be detected by PokerTracker's Tournament Detection Engine - which to my knowledge is every HUSNG from every poker site at this time, I cannot think of any network whose HUSNGs are not detectable off the top of my head.

And yes, the Prize expectation should be very different from Chip Expectation due to the methods of calculation explained above.

This is a very confusing topic, let me know if you need further clarification.
