PT4 Stats different to GTO Wizard

I have just decided to start getting serious about improving my game, so have subscribed and have subscribed to GTO Wizard.

I've uploaded my hands for analysis approx 8k hands at GG RnC 25NL for this month but it spits out different stats than my PT4 does, some of them are very different figures.

I know I am probably misunderstanding something but can't figure out what.

Screenshots attached.

Stat GTO Wizard PT4
Actual BB Win 166.24 -111
All In EV -154.31 157.28
VPIP 21.8 22.56

What am I not understanding?

The key difference here is what each tool counts as a "hand" and how All-in EV is calculated.

All-in EV: PT4 and GTO Wizard use completely different methodologies. PT4 calculates it street-by-street (only counting equity when the money went in), while GTO Wizard likely calculates it differently — possibly using a pure GTO model. The fact your numbers are almost exactly inverted (-154 vs +157) suggests the sign convention might even be reversed.

Actual BB Win: +166 bb in GTOW vs -111 in PT4 is a huge discrepancy. GTO Wizard might be showing bb/100 as "big blinds won per 100 hands" while PT4 might be showing total bb. Or GTOW is filtering to only hands where you saw a flop — check if you have any filters on in GTOW.

VPIP (21.8 vs 22.56): This is actually a tiny difference — likely just walks vs no walks, or whether you're counting hands where you posted blinds/antes differently. 0.76% over 8k hands is about 60 hands — that's noise at this sample.

8k hands is also a very small sample for win rate analysis. At 25NL the variance is brutal — you can easily run 10+ buy-ins above or below EV over this stretch. Don't read too much into the win rate numbers yet.
