Ty,

Do you know that if you run 1.25 under the altitude factored index for the record, that you don't get the record at 1.25 under? It's LESS than that, and it varies dependant on which altitude track you set it at and the correction factors applied when it's factored back to sea level. So then it really isn't a 1.25 under run, and shouldn't be the cause of a HP factor. But we have no clarification on that either!!

The fact that NHRA personel previously had to do a bunch of paperwork to figure this out at altitude tracks is the reason they just let altitude factored runs go until now.
