Here's a closer magnified look at a few corner sequences, where it's full throttle into a big brake zone, then tight 3rd corner gear, then slowly opening up onto a straight, then into a really fast sweeper followed by a huge brake zone into another tight, slow 3rd gear corner. Once under braking and/or the car loads up, you can see the first really low dip area, and that's where it seems oil is in the head's or sloshing in the pan and there is no pickup.

Again, it's not horrendous looking at this, as the revs are in the high 4K, and pressure is about low 40psi's, but would be nice to see another 10psi or so, to try and keep that magic 10psi/1000 RPM. The next big drop toward the right end of the graph starts with a 100mph+, long sweeper, so you can see how it slowly loads the head up with oil, and/or is seeing some starve in the pan. I dunno.

Then followed by the biggest brake zone on the track, again, pressures seem relatively in-line with RPM, but it's just the huge swings that are so alarming.

I guess I need to just chill out more, and understand part of this is the 2-stage oil pump, or should I be more alarmed. High of ~90psi, low ~35psi. I dunno? I need somebody more data-smart to interpret this better than I can. I just drive that car...lol.
