Hello, I don't quite know where this number Daily Upvote Cost =0.358$ comes from.

This is my calculation:

Daily upvote received 0.41 -> 0.31 (after curation) x7 = 2.15 a week
Daily upvote cost 0.05 -> 0.04 (after curation) x 7 = 0.26 a week

Adding 300 sp delegation (currently 100% upvote for this amount is worth 0.03), I don't think it's that bad :)
