I don't THINK that the current Process (capital P) considers aero factors, nor will it try to differentiate down to +/- 50 pounds. I don't THINK, anyway.
Fair enough, but if any new car, or car run throug the realignment went through the same process, and if the PTB feel that a 50# granularity is acceptable, then there is no harm to the process or class done by classing the S-roc at process weight.
