I like the concept but I think it is counter intuitive as this means there will be alot less HBD being generated and dumped which could potentially impact the peg.
It also means people will be getting less Hive for their posts as quite often HBD increased enabling people to get a bit more rewards from their posts.
I prefer the more frequent power up model. Is it a challenge to assess people over a month and reward them based on their monthly Hive power up activity?
