I always check a engine with it warm, with the throttle open, 10 rotations of the crank. I typically get 165-175 on 1fz engine here in boulder with the stock head gasket and no work on the head(typically before I do a head gasket).
I have done on my own engines before and after compression reading during/after trips to sea level and elevation, and have not found a difference in the compression in the past.
You are getting a lot of information both here and on mud. Good luck
