These stats should be the same.
(Check Flop as PFR and Fold to Turn Bet OOP SRP%)
(Check Flop as PFR and Fold Turn OOP SRP%)
The difference in definition is one defines the “first PFR” and the other says just “the PFR”. Both of these stats are for a SRP, so “The PFR” is always the only raiser.
Am I misunderstanding something here?
