[s-cars] Accurate Drive-Train Loss on UrS?

[Joseph Pizzimenti]

Cody,
Don't live by the numbers, you'll drive yourself
crazy.  Dyno numbers vary with altitude, correction
factor, ambient temps, what the dyno operator had for
breakfast, blah, blah, blah...

Who really cares if it's 380 or 396?  If you put down
317 to the ground, not much else matters.  As long as
you have fun with it and love driving it, who the f***
cares?

But FWIW, upon talking with a hub dyno operator round
these parts, he goes by 25% drivetrain loss.  Others
say 20%  But whatever makes you happy, man.
