I did a quick check on the Michelen site and they used 28 and 29 psi respectively to illustrate top performance for braking and cornering, as compared to 15psi (pretty poor) and 7PSI (dangerous). I shouldn't have thought a couple of psi either way would have any effect on real world performance.

That said every car is different, and things like sidewall stiffness and curvature have their effect too.
