As Boss330 mostly explained, drivetrain losses are not a correction or "fudge factor" simply showing the difference between stated and measured power. It is best to increase the clarity of such statements are use an actual crank hp measured and a fixed drivetrain loss. Granted getting the latter is not easy, thus most dyno guys use some fixed value and often 15%. It's really a shame if folks call your number a 5% drivetrain loss as that is physically impossible and really impedes understanding. Buck the trend, post the right way to discuss such numbers.
Boss330: Can you please translate the quantities in the upper left hand box of results?
