Having re-fitted my oil pressure gauge I revistied the manual to check the min pressure specified by Toyota. I cant seem to find it - all I can find is the absolute min at idle of 4.3psi. Thats REALLY low lol. I've looked through the big green book from Toyota and they dont specify oil pressures other than this, and certainly not at different revs. So for now I'm just keeping an eye out that the pressures don't change. It'd be nice to find the correct values though.

The only oil pressure specification I've ever seen is at idle. The only thing you can do is make sure oil pressure rises with engine RPM.
You would have to check the manuals for the exact pressures but an old "rule of thumb" is ten psi for every one thousand rpm.

OOh excellent! Seems they stopped giving out that info somewhere between 85 and 90 but mine falls in line with the upper end of those so I'm less concerned now - cheers!
