Having ADV affect what we see as currents is probably a bad idea. Not the worst idea ever, that's dynamic budgets, but bad nonetheless. Regardless of what it affects, some owners are going to run 0 or low. If it's too many in a world, trading will become impossible. What a guy sees with 0 ADV will be vastly different than what a guy sees with 15m. That will lead to vetoes of fair trades, causing an uproar, or approval of bad trades, creating an imbalance. Neither of those are good for a world or HBD.
