I don't quite understand how it works either, my dear friend, but those are the numbers. It seems that if a post (at least in Hive) hasn't reached $1, and we vote for it, there is a chance that our vote will become more effective when a strong vote reaches that post.
Here's another shot:
I can barely read that.
What is efficiency? And why can it be greater than 100%?
Oh! I'm sorry. Efficiency is how effective your vote was on the post. From what I have been able to observe, it depends on how much money the publication has accumulated at the time of giving it your vote; If it is less than 1 dollar, the chances that your effectiveness will increase are high.
Okay, well none of those votes were within the 5 minute period after the content was made. The least one is 9 minutes, and that one has almost the lowest efficiency of any of them. Hmm.
I'll show you other examples on this topic (and that I keep digging to see where the secret is) of two users, whose APR's are different, and also their voting times.
One vote after 5 minutes:
and the other, before 5 minutes.
Something had to change in Hive, or we still don't fully understand how rewards are calculated, at least in Hive.
