Here is a video file from the Marine Dr on compression and spark test - He clears up the throttle open or closed issue when compression testing but doesn't state cold or warm all though it appears cold...

I did some quick research and there seems to be a recommendation towards a warm engine. Everyone does say that the warm engine may change your numbers but it shouldn't change your cylinder to cylinder comparison.
I hope this helps
