About vote changing I think it would work better like this:
"As we know after 4 July the payouts will happen about 24 hours after voting… What make sense to me is that the vote should be time % weighted… If I vote now and I take my vote back after 1 minute 100% of my vote power should be taken back(it could be even be a miss-click)…If I do it after 12 hours then 50% should be taken back, if I take it back 1 hour before cashout only about 4% voting power should taken back (1/24)… What do you think?"
