Dyno calibration
If the air/weather conditions changed he would be correct to change it. If not... that is a whole different story!

because its not making any power! Just kidding, most main stream dyno setups have their correction factors buil in to correct automatically on a SEA type correction based on feedback from its weatherstation.

I dont understand all the excitement about manually entering a correction. The auto updating weather station is really nice but people have been manually entering correction factors for many many years. As long as you have somebody that understands that and is honest about it, then that should not be a problem.
And btw.. there are probably more inconsistant things that are done that affect the testing more or as much than the on-average change of the correction factor during a test session.
Atmosphereic correction is only ONE part of it.
