For a "performance based class", there is no points incentive to out qualify, or set national records.
I envision somebody with a top performing car being able to upset the balance of the points structure against traveling bracket racers that can't (or won't; doesn't matter which) build a vehicle capable of setting records or being a top 5 qualifier. And that vehicle could be a new DP or CJ car that opens up the throttle a little more each session or it could be an old Rambler that will give it all in order to set a record or be #1 qualifier.

And in the end, the AHFS will run on an accelerated curve for those that want or need the extra points!
The current points system favors those with the $$$ to travel the entire continent and disfavors those that do not.
