I am just guessing but that sounds like a hot tyre pressure to me.
There are many factors involving what tyre pressure to run. It is always intelligent to start with what the vendor at that track recommends. You then should start tweeking the pressure from there.
1) Set your cold pressure and note conditions and temperatures (air, track, weather etc.)
2) ride the bike and see how it feels.
3) check your HOT tyre pressure as soon as you come off the track. Write this down!
4) Adjust your pressure and do over.
As an example I run 29F and 26R cold psi for most conditions. The bike is very light and doesn't have a ton of power so the tyres feel better and get to temperature quicker at the lower pressure. However when the track conditions are very cold I run 31F 28R, this will get the tyres into the Hot pressure range I prefer for the handling/response I like (ok am used to).
Bottom line is to take good notes and try different settings and see what feels/works the best for you.
