With every cylinder firing cycle you generate say 1000 degrees of heat and 500 pounds of pressure.

I would think that would be enough heat and pressure to burn and blow any excess oil from the rings in a couple of cycles. After about 5,000 cycles, just about enough time to warm and engine for a couple of "seat the rings" hits, I would think there wouldn't be much "excess" oil in there.

I'm guessing this is like a couple of other topics that show up here, opinions, but no physical proof. There is lots of "this was done, and this happened", but that is not proof.
