So, if someone ran these races all year and accumulated points, that driver would have to decide at the end of the year if he wanted to forfeit a possible "division" championship so he could attend the Runoffs? And what of the subsequent "division" winner, the guy that actually finished second in al the races? He's now suddenly the "champion" because the actual champion decided to go to Road America (to finish mid-pack)?

I understand the point, but that's pretty wonky.
