@clayop this seems a good idea, the only thing I see is that this will motivate people to place Steem on the savings account (rebranded), but that will be stack there for only 3 days, and in this way we loose the amount of people or percentage that are powering up for 13 weeks. Are you proposing this as a rebalance, some people may choose to have SP for influence in the community and some others on savings as investment?
Please let me know if I understood correct?
