That’s a good question, the post tabulator and rank determiner is a bit weird, from what I’ve read.
I think it updates your post every time you login and post again.
My original sort of thought was that it would update every time you did a new post, but that has not seemed to be the case.
So I think it’s tied to logging in and maybe posting again, and then it updates. Or perhaps it retabulates like daily and then updates you when you next post….it’s something convoluted that I didn’t get when I first read it. I’ll have to read more to understand it.
He has two posts very close together, I’m betting one after the other???
My bet is that if he logs in again and posts, we’ll see an update.
I don’t recall now, but I think one is a shadow until one has 5 posts.
