I find it hard to believe you've had 47 articles in a row curated, however, I know what you mean when you say your distributed pieces don't earn the big bucks you'd expect.
I've found that curation doesn't necessarily guarantee thousands of views and dollars but what I think it does is keep your piece in circulation for longer. I've had articles from over a year ago (which were curated) suddenly spike again for no apparent reason, which is nice.
Trying to figure out Medium and the algorithm is a neverending process and one which you'll likely never conquer. I've come to the conclusion that all you can do is write as often as possible, stay active and hope for the best.
Thanks for sharing your experiences and good luck on your writing journey 😁
