Okay, so the changes for HF 20 haven't taken effect yet. We're back to running off a version of HF 19, so nothing that's happening now has anything to do with HF 20. Yet.

It is still supposed to go into effect next Tuesday, though, providing the Top 20 witnesses all start running it and some other bug doesn't bite in the process.

So, any drop in your voting power now is probably due to the STEEM price and how much you vote.

What I was referring to has to do with voting on a post that is past 6.5 days old. Under the current rules, the system won't allow you to upvote past a certain point, but you can actually flag. They've decided that's not fair, so instead of keeping us from upvoting at all, they're going to make it possible, but reduce the effect of the upvote the closer it gets to payout. So at say, twelve hours and beyond the upvote is still 100% of whatever it is, but the closer to payout it will drop in percentage until it's basically $0.00. If a vote is worth $0.03 otherwise, it will be worth less and less the closer it comes to payout.

This change will only effect upvoting on the older posts heading towards payout, and isn't supposed to change any upvotes before that.
