Very well analyzed

The examples of the convergent curve should be simple enough for anyone to follow and is very helpful.

I'll just add that with 50% curation and 25% downvotes, for every 'abuser' at any given time we'd need 2 good actors of equal stake to bring their self voted rewards down to average (mean) curation. That is to very roughly say if two others of similar stake are attacking your vote farms, you might as well just go curate honestly.

The 50% curation number was chosen because we believe 2 good actors for every 1 abuser is hopefully attainable in the new equilibrium, and therefore is a sensible number to try on our initial attempt at economic reform.

If we lower this curation value, not only would we require more good actors per abuser, it'll also increase the pay gap between curation and abusing in favor of the latter, likely resulting in fewer good actors per abuser.

Basically the higher curation is, the higher the probability of successfully changing the status quo voting behavior to something that's broadly honest, but we also want to leave enough to reward and incentivize authors too.
