If I'm reading your graphs right, it looks like 20M Hive is no longer liquid. And it looks like 10M of that Hive got converted to HBD and an additional 0.5M Hive got burned during the process. So that seems to imply that 20-10.5 = 9.5M Hive that got "net powered up" (by net, I mean including power downs). Oh, never mind, I think I just realized I'm missing another component: Hive sent back to the DAO by the stabilizer. Anyways, would be interesting to see what the net powerup/down was for the month.
