If anyone should be rewarded, it NEEDS to be the regulars, as they finance CCS.
That is EXACTLY the attitude that has bothered me so much in dealing with so many WERA regulars over the years. "This is OUR club and we should get preferential treatment."
I think that's a bunch of BS. Every racer should be treated equally. Every racer should (ideally) be able to finish the race in the position that truly reflects how fast they were compared to other people in that race. The, for example, 3rd fastest guy on the track should not be put in a position by the organizers where they can't realistically finish higher than 15th, just because they are not a regular. Rules like that REDUCE the number of entries, not increase them.
Imagine you're a "regular" in a series that grids by points and you start the season finishing well. You're getting good grid spots. Then May rolls around and you crash and break your arm and now you're out until August. August rolls around and you're ready to ride. But now you're so far down in points that you know you're going to be gridded probably in the 2nd wave of any race you enter. How appealing is that? I'd say there's a pretty good chance you might decide to skip some rounds, or maybe the whole rest of the season and, instead, focus on getting ready, physically, logistically, and finanically, for next season.
Now, in contrast, imagine you're a "regular" in CCS (with current gridding rules) and you start the season by pre-entering each race weekend 5 weeks ahead. In my experience with CCS, pre-entering just 4 weeks before has always gotten me a grid spot in the first 3 rows. So, you're still finishing well, just like in the other series. Now, May rolls around, you break your arm, and you're out until August. August rolls around and you're ready to ride. Now, you can still pre-enter 4 or 5 weeks ahead and still have a decent grid spot. How appealing is that?
A series that rewards "regulars" is a series that has decreasing appeal all through the year to the non-regulars. A series that treats everybody equally is, at least to me, a far more appealing one to participate in.
The 2nd scenario seems to me to be much more likely to keep people coming back.
