I wouldn't be too concerned - no idea how accurate a Spa Gauge is though
Mine sits about 30psi at idle when the oil is between 80-> 90 degc
After a hard run it drops to about 26/27 when around 105 deg
Lowest I've seen is about 24psi after a few laps at Anglesey - think oil was about 115/120.
It recovered as the oil cooled
That's on Silkolene Pro S 10/50.
I noticed it used to run slightly higher psi on Castrol RS/Edge 10/60 ( when it used to be popular ). Think the reason for that was the molecules get chopped up or similar - Mike R or Oilman or Rod Tarry could probably tell you the reason.
