I agree with Dick, and would argue (to Greg) that the BMW in ITS fits his example perfectly. Car is classed at (what I believe) was an inappropriate weight. First builds do well, but are not overgods (not a typo, I like that new term). As a few years go buy, pro shops get involved and the BMW starts to win more races. Finally, it is apparent to all that the car is an overgod, and something is done about it.

The process can work. It's not always clean -- and the BMW is another example of that, as I think the SIR situation was messy and effectively ran all E36s out of ITS -- but it works.
