[devil's advocate mode]
Whilst I appreciate it's like that at National level and was the same up here with large numbers in the past, I struggle to see how reducing the number of finals to 1 for B downwards will encourage newbies and growth.
Travel 1-2hrs+ knowing that you'll certainly only get one race at the end of the day? For many drivers (if only running one class, and attending every round) that would mean only 7 races in the entire SORC season...
Surely better to reduce the number of qualifying rounds if extra time *really* has to be engineered that way?
I note everyone proposing only 3 finals for the A are folk who are pretty much guaranteed to always qualify for the A

Humble /2p from a 'non-A finaler' when rounds don't have numerous absentees
