Can you at least make their own bump power visible to each user? Might help with debugging.
Maybe later. If it's shown somewhere, I'm not sure where to put it.
So this basically means maximum possible bump power is 364?
Around that. It varies slightly depending on how the periods line up. It's as if you signed up exactly 365 days ago.
Mini bumps don't reduce one's bump power, right?
Correct.
And of course the fact that critique posts bump the topic is an unfortunate side effect.
I don't think that people should worry about this. If you're exposing problems, then it's good for it to be bumped for a while. (And if it's self-moderated, then the poster has some incentive not to delete your post, since doing so undoes your bump.) If the poster wants exposure more than anything, such that they're happy you posted to criticize, then - once people get used to this new system -, the topic will probably already have a much higher bump score than what you're contributing.
