I decided to open up my service manual pdf. Here is the page on the tech specs of the stock oil pump. Definitely says the stock spring is 50-64psi with full temp 30W oil.
I'd say the reason Joe's pressure is so excessive is because either his relief spring is messed up (siezed somehow), or hes running some thick oil.

That graph looks like it was made with a worn out stock pump. My OP is at 50psi by 4500 and 60psi at 5000. I have always been told that 10psi per 1k rpm is perfect. Even on 1k+ WHP v8s.
I'm just trying to show that there is a place where the high flow fits, but there is also a place where the std width fits. Hell you sell both, and I just bought one from you myself. Don't think I'm arguing with you because I'm trying to disrespect your product. Quite the contrary.

I don't think that at all, I usaully argue to learn.
From a bearing stand point the bearing needs the most support at peak torque, and at peak rpm. So whever the maximum torque is coming on at you want maximum pressure present, and considering how the Miata's work you want that maximum held all the way out if you can help it. Per cubic inch a 1000hp v8 doesn't have anything on this little four cylinder.

does anyone happen to have the part number for the phillips head bolts which hold the oil pump cover to the housing? i got all of them out, but one of them wound up partially stripped and i'd really like to replace it.
edit:
in case anyone is wondering, i found the part number for the screws. it is: FE1H-14-124

FWIW I measured the oil pump spring
It exerts 3.55 kgf @ 5 mm of compression
= 40 lbf/in
diameter of piston = 16 mm = 0.4 in^2
pre load of spring at rest = 10mm
piston cracks open with an additional 3.3 mm ... total 13.3mm ... that's 53 psi
each mm of motion is an add'l 4 psi
The piston has a wear mark which suggests a "wide open" position which has an additional 3mm of movement. This is 65 psi.
For every additional 1 mm of shimming, it adds 4 psi.
If you add a 2 mm shim it'll crack open at 61 psi, and it'll be 73 psi at the "wide open" position.
