For me, either you don't have tokens (which is fine by me, although it was the manufacturers that wanted them, and the fundamental reasons why they wanted them originally haven't changed), or you have tokens and everybody gets the same amount of tokens (although I do think Honda has been treated pretty shoddily by the system of guessing how many tokens they would have used if they'd been around last year - they didn't use any tokens last year so the way I see it, they should have all their tokens to use this year).
However I would be opposed, on principle, to your suggestion, for the same reasons that I'm opposed to success ballast or any other method of punishing success and rewarding failure. Everybody designed and built their engines to the same rule book. The best engine wins. We knew it would be like that from the beginning. Again; it was the manufacturers that wanted engines to be performance differentiators, because that's how you move the technology on, and hopefully some of the development that goes into the F1 project will have other applications and spin-offs.
I'm quite puzzled as to why when a rules set has been agreed, and upon implementation there haven't been any unintended or unforeseen consequences (unless I'm missing something), everybody is acting as if we have a crisis on our hands. What were people expecting?
