Andy and Darin,
I for one feel the need to voice my support for both your efforts AND your accomplishments over the past few years. Changes for safety (batteries), changes for cost containment (opening up wheel choices) are welcomed changes in the spirit of IT: giving people a place to race on a moderate budget. I certainly agree with avoiding model specific changes, and consider the new weight corrections the way to go, as it can be applied to any model.
I believe there was effort from the beginning to 'control' rotary engine potential, and that some of the rules, such as the intake porting, have gone overboard. I'd like to see the rotary specific rules reviewed, and where appropriate, eliminated.
The limiting factor to 12A rotary horsepower is the intake port area, plain and simple. The Nikki, as TAK stated, doesn't have the driveability of a well calibrated FI system (There is some black art to getting a consistent air/fuel ratio from 4K to 8K) and spark timing can never be optimized as it can with ECU control.
I'm rambling, but my point is this: without intake-side porting, such as street porting (DSR has a required template, I believe) we will not be able to increase the engine performance of a 12A to make the RX7 competitive on tracks where HP/lbs is important.
Therefore, the best way to correctly class the 12A RX7 is the method that you've instituted: add some weight, and put it in B, applying the B specific rules (wheel size). Even if too much weight is added initially, it could be corrected at a later date. In 'A', it can never be classed correctly with methods that are in the spirit of the rules.
So it seems that Dave Y. somehow snuck onto my hard drive and lifted my thoughts. Nicely said and summed up.
