The new system makes it so the power of the vote depends on the total payout. For posts with $0.00 payout a vote is worth %50 of its full value, and for posts with +20 STEEM payout (currently around $4) the votes value become %100 again.
It depends on the payout of the post and if you voted when it was at 0 then it became 20STEEM. Your vote automatically becomes %100 again.
I REALLY DISLIKE this update, but well, better adapt.
I don
To me I feel it should be the other way around, a post should leave room for the others once it gets to that kind of stake.
