Treb,i don't get your last post... changing from the 'sweet spot" psi brings you away fromyour best lap times. Therefore there is a drop-off in grip above the sweet spot. Simple as that. Throwing in a bunch of physics terms doesn't make you right when you are using them wrong. Go to a performance school. Ask if you should gradually adjust your tire pressures to find the sweet spot, of if you should pump them up to 100psi for max grip.
