Ok, try basing this estimate:
I have over 200 slips with this supercharged car, and the correction factors work tremendously well in assisting with my run predictions, down to the hundredth. My 18-plus years of competitive drag racing has given me a pretty good handle on what asmospheric and elevation corrections can make. These are then used in bracket racing. To make money.
I'm telling you that the NHRA correction factors are suprisingly accurate. I can't say the same for "people you know." I'm sure they're great folks, but physics is physics.
I could easily, using NHRA correction factors, tell you what your Las Vegas car will run in Chicago. Accurately.
Your dismissive approach of hard numbers is disappointing for someone looking for HARD NUMBERS on a dyno. As soon as those correction factors (SAE, anyone?) are there to help, I bet you're right there.
BTW, there is "ONE rule to cover all 100%" as you put it. It's called DENSITY ALTITUDE.
