I don't know exactly how curation reward is determined. It seems that curation reward depends on multiple factors such as vote weight, other people's votes on that post before @jsup's upvote and after @jsup's upvote, time between post creation and voting, etc.

Whatever curation reward @jsup gets for your post, you will get 90% of it. Remaining 10% will be used for passive reward(for those who did not write a post that day) distribution.
