Restoring a true 50/50 split from 88/12 would increase curation rewards for all voters
Also of note, giving more money to curators would reduce author payouts as a whole. But it has the theoretical potential to increase the payout to good content by improving curation.
Also, there is a non-trivial amount of author rewards that are being converted under the table to curation rewards (by funding initiatives like SG with self voting). If curation rewards offered enough incentive in and of themselves, this (at least arguably) would no longer be necessary.
Excellent points
