They are the same people complaining of understeer. I'm not an expert, but my pressures go from 35 psi cold to 40 psi hot after a 20 minute session and I see 42-44 after a 40 minute session. Yes, this will depend on the track and ambient temps and changes in track temp, but I see about the same temp changes whether I'm on a tight twisty track as a longer higher speed track.
Er I would prly say I'm entering too hot as I don't think I'm a really quick driver lol

But I do get LOTs of understeer in my car, that much I know.
Surprisingly, the couple of times I've driven someone else's car, I don't feel the same understeer.

The temps on sunday were 105-110, but it came down to 95-100
