Also is there not a pressure relief valve in the oil system? Looking at the BE oil pressure vs RPM graph, it flattens from ~3800-8400rpm.
If so, wouldn't over driving the oil pump make it work harder for no reason? Otherwise pressure would continue to always build with RPM.
The difference in oil pressure someone else measures could just be due to their equipment, or sample location.

This BE point comes to mind when you mention pressure but not flow:
"Having double oil flow over the bearing surface increases the wedge strength and keeps the bearings cooler. "
