Max compression was impressive, with 80-90 PSI noted. BUT. It was only one chamber that did this on each rotor.

Rear Rotor had 80, 65,65 or so
Front had like 85,70,60 or so.

Did anyone else ever do a cold compression check prior to first start? Should I not worry about these numbers unless they persist after we've started the engine and blown/burned out the pickling?

I wouldn't worry about it.  I think I was seeing about 65 on mine before I
ran it.  I've never checked it since.  All I know is I get good power.
