We both seem to be right! I got my 2 bar from here:
P ZERO TROFEO R, Motorsport tyres - Car Tyres, Motorcycle Tyres, Truck Tyres, Motorsport tyres - PIRELLI INTERNATIONAL
"P Zero™ Trofeo R does not usually require higher pressures for racetrack use. It is designed for use at a pressure of approximately 2 bar, to be adjusted according to the type of car. "
But, you are right... On page 18 of 20 they say 2.2 bar hot.

In the end i used 2 bar as a guideline only. I think their 2.2 bar works best for 16 inch tires as when i got to 30psi i was having more rollover on the rears than I would like. I found 32-34 psi in the rears best. I had 30-32 On the fronts, hot.
I still think their best days are in the first 10 heat cycles. My fastest lap came out of nowhere on day one during busy hpde mostly obstructed by much slower traffic. I had one unobstructed lap and I hammered out a fast lap... While basically chatting about how much i loved the car. Mind you, i was more focused on teaching the last two days when I was recording my recient laps.
In August I will hit the track hard, no excuses, record everything, and see what I get. Sometimes the more you do something, the more the brain wants to follow a (often safe) pattern, especially in schools. Maybe I need to push a bit harder. On my fastest lap i remember the car feeling a bit loose. I am pretty sure my car was far closer to the edge. In the schools I go fast, but for safety don't push to the point of causing the bad behaviour.
Still, I bet that like slicks, the big gains are early. The wear rating is 60.
