The wear pattern on the tyre seems best at 32 (nice and orange peely), and whilst the reviewer undoubtably knows what he is talking about, all of the other sources of advice that I respect favour lower pressures, especially at the track temperatures in the South of France (last July I was on track for 2 days at 39 degC!).
The higher the track & air temperature the the higher your tyre pressure needs to be, ie running at 34 - 36 psi in the rear will run the tyre cooler on a hot day than 31-32 psi in the rear.
