So, the TPE is always a bit funky but I'll try and figure this out. As you know it is an estimate. I've been paying attention to Marin's questions about this stuff and the estimates are based directly off the recent transfers, they aren't made up.
#1: The first guy is in a lower salary bracket so that's why his price is that way. The awful and pitiful average out with the Prolific and strong to make him seem like an average player BSP wise which is the only thing the TPE looks at.
#2 and #3: Higher salary bracket and I can't see how many recent transfers but it's likely due to that number being so low. The third one has 5 recent transfers meaning it's basing it's data off 5 players while the second may have had some better builds coming through recently.
With the TPE I always pay attention to the number of recent transfers and brackets they are in, that would be my only reasonable explanation.
