It doesn't seem to be very well known that @dtube has its own curation system laying on top of the basic Steem curation system. They take 25% of author rewards as a beneficiary reward and then distribute some percentage of it to voters on DTube posts through transfers from the @dtube-rewards account. As far as I know this isn't documented anywhere, and I had no concept of how much of the beneficiary reward they were redistributing, so I thought I would look quickly, and it would make an easy post for a Sunday.
The first post I looked at was this one by @art.life, which gave up 18.556 STU to its beneficiary reward. Converting that to Steem at the current feed price of $1.55 we get 11.97 Steem, and the curation algorithm paid out 7.276 Steem, or 60.8%.
Then I looked at this post by @dronemania, which gave up 10.8075 STU = 6.972 STEEM to its beneficiary, and paid out 2.289 Steem, or 32.8%.
But wait: @dtube voted both of those posts, and DTube doesn't pay out curation to itself. So I looked for some posts that didn't have DTube votes, and picked out these three:
This post by @rainbowboomx paid out 0.435 STU, 0.281 Steem, and curation paid out .28 Steem, 99.6%.
This post by @snowynight paid out 0.168 STU, 0.108 Steem, and curation paid out 0.099 Steem, 91.1%.
This post by @tonysayers33 paid out 1.864 STU, 1.202 Steem, and curation paid out 1.178 Steem, 97.9%.
All of those numbers are close enough to 100% that the difference could be accounted for by the several iterations of rounding error - Steem in the beneficiary payment, DTube in the curation algorithm, me in the analysis. So I think it's very likely that DTube pays out 100% of their beneficiary rewards to curators, except for those that would have gone to the @dtube account. In any case the percentage is at least in the high 90s.
This means that total curation on dTube posts is in the range of 40%, for those of you looking for higher curation percentages. Even better, the dTube portion pays out in liquid Steem rather than SP.
I still don't know how their curation algorithm works, other than that it's very different from the one operating natively on the blockchain. I might look into that later.
