5. Don't worry any action or non action will cause people to write and complain. It is an unfortunate reality.
The bottom line is that some amount of data has already been determined to be enough to justify variation from the norm in the classing process. The ITAC should keep records of when cars are classed, or re-classed. Look at the cars you classed 5 years ago (or 3 years, or whatever the members of the comittee agree is reasonable). Check to see if any of them are being raced. If they are then go look for data to support expected, or unexpected power gains - I know you can't just look it up in Wikipedia, but you can talk to competitors, engine builders, ITAC members with experience of that engine. Convince yourselves that there is no reason to make a change and tick a check box in the record for that car to indicate that you reviewed it. If there are no cars racing, leave it as is, but check in on it each year when you do this review to see if it needs to be cosidered.
That is an off the cuff shot at a process to do this. It reads like a lot of work, and there is probably a few alternatives at every step that would be better.
You can't pick and choose where you apply a different standard. If it is accepted that some cars don't respond the same, and it has been decided that those cars will be treated differently, we must develop a mechanism to identify those cars on an ongoing basis.
