Thanks for the reply, 0.358$ comes from (0.038$ + 0.32$)

0.05$ (-25% curation) = 0.038$
300SP for 1 day potentially gives 0.32$ worth of self upvotes (1 x100% upvote every 2.4hours and no curation gets substracted)

I'm not complaing by the way, I just try to break down the numbers the way they are. I do think it's a huge problem for steemit that self-voting is often by far the best thing that can be done. Even a great project like Hive account@qurator seems to be giving a loss compared to just doing self voting. (I would have to go through the numbers for the other options, but 7x 0.05$ upvote + 300SP delegation right now very much feels like using an upvote bid bot where 0.358$ gives back 0.31$)
