I post here my blog posts that I believe are interesting for the community, but I never repeat it. Let the algorithm take its course.I remember someone studied the best times to post, but if everyone does the same, it changes the best times.

It was posted three times. In consecutive days, in order

#1 https://news.ycombinator.com/item?id=47985042 4 points (by the OP)

#2 https://news.ycombinator.com/item?id=47994401 2 points

#3 https://news.ycombinator.com/item?id=48000028 425 points

The submmiters of #2 and #3 look unrelated. Sometimes it happens, the author post it and later someone else is more lucky with a repost.
