You voting power replenishes but with 84 SP, the vote isnt worth much. It isnt worth zero but it is only worth .001 or so.
Voting power goes from 0-100 based upon how much voting is done. It replenished 20% every 24 hours. But how much that vote is worth is dependent upon SP owned.
Thank you for your feedback. Many have responded and I think I've finally got a grasp of how it all works even thought it took me an embarrassing amount of time and reading to get it!
