I just noticed that I got a 3.57 score for the curation table. Which is quite a miracle I would say, since I basically didn't do anything. I had like 4 users in Steem auto being upvoted after 0 minutes, so this should not give any curation. Two other Steem auto users were upvoted after 28 minutes, which should also be far from ideal. And like 5 times a week I just upvoted something in less than 2 minutes.
I did not even use all my 70 upvotes. Otherwise I could have managed to get a 4.5 score.
Time to amend your voting to maximize this score then :D
