If this is HDPE, your tires will likely pick up several psi while on track. By the end of the day my TPMS was yelling at me because I would go out on track with 28 psi but would come back at 38psi which is well within spec.
As a basic rule I've always taken tire pressure readings immediately once I'm back in the paddock and drop the psi down to whatever the recommended level is for that tire. Over the course of the day this should require little or no adjustment beyond the second session.
