> Something like: 10^26 FLOPS * 1.5^n where n is the number of years since the regulation was published.

Why would you want to automatically increase the cap algorithmically like that?

The purpose of a regulation like this is totally different than the minimum wage. If the point is to keep and adversary behind, you want them to stay as far behind as you can manage for as long as possible.

So if you increase the cap, you want only increase it when it won't help the adversary (because they have alternatives, for instance).
