I'd be curious to see how the pressure drops track with RPM. IE, does 1G at, say, 3500rpm show a similar drop pattern to 1G at 6500...

Oil cooler has nothing to do with lateral g oil pressure drops. KillerBMotorsports is just concerned the pressure drops too much when oil temperature rises while I felt it is just normal oil viscosity change when oil temperature is higher, which is why I would like to try slightly higher oil weight in summer.
at 3500rpm the oil pump is pumping less amount of oil per sec than 6500rpm. We saw this pattern at Laguna Seca T4, where if we keep the car at 3rd gear redline, there will be brief oil pressure drop but if upshift to 4rd, the RPM will drop to around 5000 rpm and the oil pressure remains normal. So presumedly if you drive the car on track below 6k rpm, maybe you will not see any oil pressure drop at all, but then you will be much slower.
