Oh got it now (or so I think). So, if a user wants to cash out quickly, a bigger percentage of this entire stake, he can do it once, for an amount set at 10%, let's say, but then he will have to wait for a while until his/her "withdrawal power recharges. That's an interesting way to put it but I doubt it will be easy to understand and I have no idea how many users can actually grasp it. But I'm writing it down as a further improvement, once the participation is really big.

Thanks for taking the time to explain :)
