My PERSONAL experience with the NT01 is they were much more stable over a 20-minute session if they were coming in 37-38psi hot.
You really just have to pick a baseline cold pressure, and see how much you pick up over the course of a session, and then adjust. The car will start to get slippery once the temps and pressures get too high, so back down a couple psi until the car is sticking throughout the entire session.
There is no one "right" answer; it all has to do with car setup, weight, and driving style (oh, and let's not forget ambient temps and track surface temps! )
