Yeah, so???? He’s not talking about CF errors using the same CF across the country or around the world. He’s talking about an inherent flaw in the CF and it’s the same error regardless.
And that error only affects the actual power the engine makes. In other words, if we both use the same CF our numbers should match. You can
test in Denver in August and out here on the west coast in October and the corrected numbers should be the same.
