Bonneville- 4200ft +/- elevation, El Mirage- 2840 +/-, traction is different, some of the same vehicles run. Mojave Mile- 2791+?- , Loring- 746 +/-, Wilmington- 1077,etc. Pavement offers better traction. Run 1.5 mi. at the long track, along with 1 mi. and 1 kilo. 1 mi. & 1 kilo at the mile tracks. Certification of a record would be according to a "to be" developed criteria. Seems to work for the ECTA. For example, Bill Warner's run at Loring is the fastest sit on motorcycle ever timed, to my knowledge. It's certainly widely known. Point being, would that record have more status over the long run, and as a historical marker, if it was recognized by a national or international body?
