I don't think tire temps are useful in the HPDE format.
If the main concern is tire life (aka how fast will I ruin my tires), I take tread depth readings before and after the event and then I take hot pressures after coming off track.
But why did you continue to run the rear temps lower throughout the day. I would have went with 34psi all around from the start. Maybe 34fr/33rr if you have MDM on or a twitchy right foot.

You might have to be a member to get it, but from what I've seen so far it is worth the cost of membership. Very nicely done.
Hmm...that would be awesome so I'm not showing up to the track guessing and then running the latter half of my sessions with NT01s being overinflated and somewhat more skittish. The Hankook RS3s really spoiled me. They did really well from 35psi - 42psi, very little difference in grip.
