Yeah, I think rather than wondering about different tradeoffs, we should just start with the inverted 3.5 day mechanism. That addresses the fundamental supply imbalance issue. If it then turns out we need something faster to provide more stabilization against short term moves than what people doing short term trading and market making provide, then we can add something else.
Let's start with the proven mechanism and see if it is enough. It think it might be.
(Yes I wrote the above before your last comment.)
