Hello. Just a little hint. After Hardfork 20, the rules on curation rewards have changed so that if anyone, including the author of a post, upvotes it during the first fifteen minutes, they lose between 100 and 0 percent of the curation rewards as that portion goes back to pool. Because the share of curation rewards from a post depends on the SP of each of the curators, the voting power they have, the voting percentage they use, and the order in which they upvote, it makes most economic sense to upvote when between 9-13 minutes have passed since the post was published. It is advantageous to frontrun curators with much SP but not too early.
