skewing the dyno??

When was the last time you heard a guy say hey, my dyno is a bit hot? You never hear that.

If you want to know if the dyno is producing correct numbers you look at fuel flow and OBSERVED horsepower.

It’s simple math. Then you’ll know.
I wonder about Nick's Garage dyno. His numbers seem low to me for the builds and what other people's dyno shows for the same type of build. Then again, maybe his is accurate and not inflated.
