Want to add: Lowering velocity of SP regeneration from 40 full weighted votes per day to 5 per day.
As I showed for Golos network, regular monthly active users cast only 3 votes a day. 40+ votes are normal for bots and super-curators which sit on Steem 24/7. So reducing SP regeneration will shift reward balance toward to regular users with normal life (aka work, studying, eating, showering, etc.). Regular Steem users will note that their votes become 5 times greater. And that's good both for curation quality and new users
involvement.
