I've been banging my head against the wall for the past few days, staring at a dazzling inconsistency between the rewards displayed in Steemit (next to the posts) and the actual rewards (displayed in user account -> Rewards tab).
This inconsistency potentially led to some strange values in steem.supply as well, so, until I figure out the math behind this, (if there is one), I think it's better to treat the values there with caution.
I'm writing this post primarily to learn how this is actually working.
What You See Is NOT What You Get, It's More
But how much more? Let's look at an example. This is what is displayed next to a post for which I already received the rewards:
So, the author share of this should be 75%.
$35 * 0.75 = $26.25.
But Steemit says I got $29.00. First inconsistency, checked.
Moving forward, let's see how much did I really get:
I have no idea from where these numbers popped out. But let's try to convert them all in STEEM / Steem Power and see if it checks out, somehow.
8 days ago, you would get 2.6 STEEM for 1 SBD.
So 14.499 x 2.6 = 37.8 STEEM.
Add to this the Steem Power: 37.8 + 2.4 = 40.2. Second inconsistency, checked.
And multiply this to the market price of STEEM 8 days ago, roughly $2.89:
40.2 x 2.89 = $216.17. Although the post says I got $29. Third inconsistency, checked.
A Potential Solution
If I divide the actual rewards in USD to the rewards displayed in USD in Steemit, I get something that may start to make sense:
216.17 / 29 = 7.44.
$7.44 is close to the price of SBD at the moment of posting.
That may suggest that what you see in Steemit is the value in SBD (a claim which is supported by the value returned by the API calls, which is something like "32.47 SBD"). In this case, the fact that Steemit presents those rewards as being in USD is quite misleading. It may be a legacy thing, from when 1 SBD was 1$, but this is not the case anymore.
Also, this doesn't solve much about the first inconsistency, the one about the author / curators split.
I'm still trying to find some predictability in this, taking into account price feeds and market feeds, but at the moment all I can do is to accept that I didn't find any acceptable one yet, and to issue a warning about how potential rewards are displayed in steem.supply.
You may get more than what it says in Steemit, less that what it says in steem.supply, or a different value.
The only one that is guaranteed to be accurate, is the one you actually get in your wallet, after 7 days.
I will post an update once I get the hang of it.
