I believe it!

For comparing times - I don't know which category of Boxster is best for me, sometimes I think F class would be the closest match, but I like to use Spec Boxster times to compare my times with, at least it gives me something fairly constant to compare to.

For example, at Roebling the SPB record is 1:23.602 and my fastest lap there is 1:26.326, so that is 96.85% of the record. Then I look at some other tracks:
  • Roebling - 1:23.602/1:26.326 = 96.85%
  • Sebring - 2:29.109/2:43.698 = 91.09%
  • Road Atlanta - 1:38.834/1:49.171 = 90.53%
  • Carolina Motorsport Park - 1:47.67/1:58.87 = 90.58%

So either I am ahead at Roebling, and a lot slower everywhere else, or else Roebling has a low SPB record

I don't get to Road Atlanta, Sebring, or CMP very often, like once every year or so, and when I do I usually pick up 2-3 seconds, so maybe after a few more times there I can whittle down and get closer

If I can get to 96% of the SPB record at those other tracks, I should be able to run:
  • Sebring - 2:33.9
  • Road Atlanta - 1:42
  • CMP - 1:51.18

But those times look pretty optimistic to me, which maybe means that Roebling has a slower SPB record. Or maybe I just need to pick up the speed more there

I use Rennpoints, and here are the SPB records at UMC:

PCA Class Records

Looks like a 2:18.252 set last year, the lap you shared in the other thread was a 2:22.54, which is (in seconds) 138.252/142.54=97% so by my metrics that is smoking fast!
