Is there a way to roughly figure out what Reduce Posting Rewards at 10% would do for the powered up APR currently would be we looking at something crazy small like 3.25% from the current 3.10% ? Or would it be more drastic like 5% APR at current numbers?

IMO and what I've been saying since the first day of 20% APR is it's not really sustainable it would crash at some point. But to me it also feels like it sucks the power out of hive. I feel HBD should be more around the 5% - 7% APR range. That feels sustainable while still proving a little more value to holding Hive and being active with it compared to just sitting around on HBD.
