Anything above 0.05A(50mA) is generally considered an electrical leak/short circuit somewhere.
I think some modern cars can be exceptions.
One good way to cook the meter during this test is to turn headlights on.
Hopefully the safety fuse in the meter kicks in before the cooking.
BTW, Macka, I reckon it's worth considering your post above in "RB30 facts, figures & helpful figures" thread with a heading like
"how to find and electrical leak" etc. I know it's not exclusive to RB30, but will help generally anybody, I reckon.
There are good youtube videos on this subject, but generally not many clearly, compactly written guides.
I like EricTheCarGuy videos. He's a no bull and entertaining automotive educational video maker.

I learnt to do the parasitic draw test for the first time from the above video.
