I imported my entire pt3 database into HEM, and i'm noticing discrepencies in the stats. the total hand samples are nearly identical, so the stats should be the same between the two programs. Most of the stats are only very slightly off, like vpip/pfr are usually less than 0.2 off. wtsd w$sd are about 2-3% off, and the one stat i'm really having trouble with is fold to 3bet. HEM is giving a much lower fold to 3bet for everyone. for example one player i have 7k hands on has a 83% f3bet on PT3 out of 120 chances. but HEM has this same players as a 50% f3bet out of only 32 chances? Could someone explain to me why the differences are occuring, and specifically why the fold to 3bet is much lower on HEM?

from my session today i have identical hands between pt3 and hem, so the stats should be exactly the same.

my HEM line looks like this:

vp/pfr/3b/f3bet/steal/wtsd/w$sd

15.0/11.1/3.7/65.2/25.7/25.3/54.1

from pt3 it gives this:

14.8/10.9/4.2/81.5/26.6/25.3/62.2

some of these numbers are drastically different! pt3 says my w$sd is 62% where hem says it is 54.1!!!

now lets look at how these numbers differ since the beginning of june (exact same hand sample in both):

HEM: 15.7/11.5/3.1/64.1/33.5/22.4/50.8
PT3: 15.5/11.3/3.3/81.2/34.1/22.5/53.9


The big differences between f3bet and w$sd really bother me

I can ask the developer to reply with specific answers, when he has time. I am definitely not qualified to answer this, but I did a bit of research to get some links to definitions and formulas for PT3 and HM. I don't think I am able to explain the difference, so I would rather not give bad information.

Fold to [PF/F/T/R] 3Bet (Folded to Pre-Flop/Flop/Turn/River Three Bet)
Description: The percentage of times the player folded when facing a three bet (re-raise) in total, or preflop or on the flop, turn or river. This includes all folds when facing a 3-bet, regardless of any previous action the player has or hasn't made.

Formula: [ Total Times Player Folded to 3Bet on (PF/F/T/R) / Total Times Faced 3Bet on (PF/F/T/R) ] * 100

The fold to 3bet stat in HM is when you first raise, someone 3 bets you and then you fold. As far as I know, PT3 includes hands where someone raised and then another player 3bet and you fold which is really misleading.

With VPIP/PFR PT3 will include hands where you are in the BB and everyone folds to you. So, for example, if you played 6 hands and VPIP in 2 but in one of those 6 hands you were in the big blind and it was folded to you HM will give you a VPIP of 40 (2/5) while PT3 will give you 33 (2/6) which again is misleading.

Not sure about the WTSD% but again I'm pretty confident our stat is the correct one
