Somehow during this exchange my point got lost. So I will repeat it
once more. IF THE ENGINE HAS SAT FOR AN EXTENDED PERIOD, you need to
squirt a little oil in the cylinders before doing the compression test.
When the car is run the small hone grooves in the cylinders collect oil
from the oil rings as the pistons go up and down. This lubricates the
walls so there is not extensive wear from the rings. The oil remains in
the grooves even when the engine is off. But if it sets for any lengthy
period, the oil will gradually dissipate. So the cylinders are not
really dry when you start it up unless it has been sitting for a lengthy
period.
That is my story and I'm stickin' to it.

You run an engine dry every time you start it. By your reasoning you
should pull the plugs and squirt oil into it every time you start it.
Most modern engines outlast the car they're in. "It's a fact"
I guess it all depends on your definition of "Right", RIGHT?
I would argue that running an engine (even while testing compression)
with rings scraping on dry cylinder walls is absolutely WRONG!
