Oh yeah, I see the flaws and certainly wouldn't suggest this "system" for serious comparison. It was just for fun (well actually it wasn't much fun - made me feel like a turd).

The only cars I can compare with are very similarly prepped (not prepped at all) S-2000's. That's why you see the "Next S on OEM's" note where applicable. Those numbers say I'm driving well, comparitively, with anyone in the same set-up (or lack of).

It looks like I need to do some Miata club events and practice the first gear evil little courses.
