Thanks timcliff for clarifying off-line.. Basically we are not looking at vote Spam. I think we agreed: It is technically not correct to say dolphins and minnows get more influences. The reason: now a dolphin and minnow can vote on a high paying post and see the price move more under n^2 just like the whale does. All accounts are equal based on their Steem Power. And yes n log(n) would treat balances fairly too.
