Here's one way you can test the tire pressure theory, on a closed course.
Do a little burn out with the stock pressure, then lower it down to 18-20 lbs, and do it again.
You should have a nice even contact patch, observed with the acceleration scuff marks, with the stock pressure, as the tires are designed to run at the level.
When you go too low, you should have dark outer edges, and light or very little marks towards the center, as the tire will bow from the lack of pressure, which causes the over deflection.
I learned about over defelection years ago, while in Accident Investigation school. You would be surprised how many people run with tires pressure which is too low, because they won't take the time to check.

If you go to Atco's website, they make no mention of it being a level or sloped surface. If you go to NHRA's website, no mention of either is made as well.
Anyone near there that could take GPS readings at the staging area and finish line? That would indicate proof, yet I'm not aware of anyone who has done so.
So far, all I'm going by is Google Earth, which indicates a downhill slope. That is, however; more evidence than there is indicating it it a level surface.

They're off by 10-15 ft. most of the time. You can't use google earth to check the elevation on a small area like that, it's completely worthless.

Some mapping software has accurate stuff, but google earth might be using outdated quad maps.

I checked different websites for elevation info, and depending on the source, it varies anywhere from being listed at ~33 feet or ~90 feet.

I hitting that "downhill track" again tonight but the temps are much warmer, around 70 degrees now. Borrowed a helmet too. And I'll post up any decent slips...hopefully better ones.
