Below is my reply.
Do you know how Points are effected by doubling up? Or even if a Masters races only Masters then jumps in an open race @ the end of the year? I was thinking about htis last night.
The simplest method seems to be like VERGE points(Though I really like Crossresults.com). The first race is by registration or last years overall. 2nd race on by points total. Give everyone who finishes in the top 20 points. That's your call up. To me the simpler it is the more likely the promoter is going to do it.
The caveat to this would be the multiple series' in KC. Thus back to cross results.com. Then mid season upgrades as well. This seems like a topic for post race beers. TO be hashed out in a round table/cage match free for all. But I'm glad someone is addressing the issuing since as the fields grow some means of orderly call ups will have to be implemented.
