And that $0.530 is only if every remaining vote is used. A lot of people do not vote. Not sure why, but I have seen people that only vote 2 or 3 times a day, and sit at 100% vote power for multiple days, and not just new users either, minnows on up to whales.

So as you said at "least 1 vote" in a seven day period. I think it is likely higher than that, but is certainly does not even come close to the real total number of votes available per day per account. Can you imagine the conniption fit the self serving whales would have if every non-self serving voter all voted for someone on a Tuesday, and used ten 100% powered votes. The reward pool is based on % after all. And just imagine all the smiles on the newusers, minnows, and dolphins that received those votes .
