Default SAE vs Uncorrected?

Is it better to compare forced induction cars uncorrected?

I've been comparing cars with different power levels and noticed when uncorrected in good weather they pick up a lot of power vs sae.
Two cars with similiar power make about the same sae, but if one of the cars was dynoed in better weather it makes much more uncorrected!

Your thoughts?

Your thoughts?
Because actual power varies with intake temperature and barometer, that's what you see uncorrected, the ACTUAL HP output. SAE correction is there to try to level all the conditions to the same condition using an equation based on a "cookie cutter" engine configuration.

That engine config is not an FI engine though and the dynamics are so different it's not effective in certain ways.

That's all I'm typing out, this could get very, very, very long.
