racing at the weekend and i was curious if when setting tyre pressure, do you take in the rise in the daytime temp in to consideration?

setting the tyre pressure at 20lbs, but after the race it would rise to 22lbs. you wold think this would settle after 1/2 hour but it didnt so before the next heat i let out some air and and took it down to 20bls again. so reducing the origional tyre pressure down to 18lbs.

as the day went on it got even warmer so kept reducing the tyre pressure to stabalise the trye pressure and keep it at a constant.

is this correct?? i mean how to you adjust the tyre pressure rise due to day time temp rising or do you set it by your first tyre reading in the morning and use that figure to work out the psi in your tyres.
