This is actually really helpful to know! I was wondering what those comment rewarder rewards that just showed up on my feed today :) So now I can vote big for posts I really like with 100% that have at least 0.02 HBD regardless of my low max vote and can vote 1% on things that don't yet have 0.02 HBD payout yet.
