Moderators, if you added a history term with a step and exponential decay to the rep, it would work much better, and need only one ODE and a few params, even a linear ramping term would be useful to make it so the better posters can get rep faster by recovering faster, for those that care. Personally, I like to give, which is why I propose it.
Embedding it in HTML is probably a huge pain and resource drain that I don't know about or understand. If used, however, the term would step from rep0 to 0 with a rep step size and decay exponentially back to rep0=1 in the time when one isn't receiving rep with a history rate constant.
However, I don't expect this to ever happen because I don't understand your difficulties and obstacles, and you probably already thought this up already and realized the difficulties that I can't as I only code to solve equations and write algorithms. Anyway as a scientist/mathematician, thanks for humoring me if you read this.
Thus, this is not a criticism, more like an idea of a utopia I suppose.
Further, I appreciate the job you do, as the NB is special.
