Can someone explain the points system?

I know that but do they count up the individual class points or just the overall points?

basically 400 points in 12 months.  I think I'll go for it next year.

Overall. You can refuse the white plate once, with a petition to CCS.
They reserve the right to refuse your petition, so cookies may help.

Me and my gal Betty (Betty Crocker that is) can make some mean Brownies!

Shoot, if they only count the overall points, I'll have to move myself up. 

Thanks for the answers folks!

I know the performance index formula, but what is the formula used to calculate the P.I.-adjusted points?

Overall points * Overall PI.  however, this excludes certain classes that don't count towards regional championships (see rulebook or list).

I want to make sure mine are correct.  My regular points calculations don't match those of CCS, so I doubt my adjusted points would match.  Additionally the points printed out at the track don't match what is on the website.

Don't know what to tell you.  I track my stuff personally and calculate every race and weekend in the same manner that CCS does, so if there's a problem, I instantly know it (like the ACC weekend, and them missing certain classes, etc) and can get it resolved.
