Can anyone point to proof of this fabled "less than mtx drivetrain loss" figure?

I've asked before yet no one has been able to produce any evidence. It seems to me alot of people are taking this as fact and I just want to know where's it's coming from.

From what I know, only one person here has had level-10 work done but has not put the effort to dyno before and after.

Sure, it could be stronger, firms up the shift points, and with a higher stall which would be quicker out of the hole but that doesn't mean it's going to be more effecient at putting power down than a manual transaxle.

If I were plucking down over 3 large for this, I sure as heck would want some type of proof because I think you could do alot better with an upgraded swap.
