you have a pressure gauge accurate to 0.5 psi and you are using a recorded difference of 0.5 psi as significant data?
so... um... well good luck with the research.

The gauge is graduated in half psi increments. The gauge is dead on other wise.
I know this because I checked it against a master gauge calibrated in 1/4 psi increments.
Unfortunately I do not have a climate controlled lab with double precision instruments, but my measuring equipment is a lot better than what most people have.
Alot of people have tire pressure indicating tools that cant even detect a pressure change in their tires after driving. This is partof the reason people believe nitrogen doesn't change pressure in a tire as it heats up.
