use a good calibrated gauge and check often
big slicks can change 1 psi just by the weather getting 5 deg warmer and opposite as night falls.
like 9 lbs at rest pressure will go about to 9.6 after the burnout. also check press after the run return road so you know ho the friction coefficient heated the tires top end
if you were running too low to start it will get much hoter and squirrley on big end.
optimise the patch contact based on the roughness and rubber quality already laid down.
good idea to have a crew member check before burnout, after burnout.and walk on the start line rubber with rubber shoes to calibrate the "stickness" and adj appropiatle.
eventually it becomes second nature.
also remember a 1/2 psi diff side to side will cause drifting and we dont usually want that.a durometer test of the tires daily is best.
i would put in a perm optical pyrometer over each rear tire and one of them modern pressure transmitters found on the expensive cars now on each tire. leave NOTHING to chance as the start line is random enough as is
