Yep, the EDSI APY would decline to around 17%. It will speed up the flipping but only by a little. After throwing a few numbers in the spreadsheet and factoring in we'll be getting 100 HIVE less a week from eds-vote powerdowns soon, it looks like the decline would be 0.04% a week. Not really much closer to the flipping to be honest, it will speed the process up but it really depends on how much income will can produce. If there is nothing we can delegate to, we're stuck with HP curation.
Had thought about upping the returns for EDSD but not so much for eds-vote. When I set them up, the eddie-earner account had around 120k HP. So i allocated 180k EDSI tokens thinking if eds-vote and EDSD got 2 hive for each EDSI minted, that would be 360k HIVE powered up to eddie-earner ensuring that the account would have at least 500k by the time all EDSI were minted.
