I have been upvoting between 7 and 9 per day, and the age of my posts should be well within the 7 days, but logged in today and all stats were 0. upvoted another 5 today. seems to have all gone bad since i promoted 2 posts on steemit yesterday. i cant change the promote option there as yet. not enough SP. i'll stick at it a little longer, but as of yet, nil upvotes for me today.
