It's almost impossible to understand the scoring of Hub. One day your scores are up and a few days later they are not quality material.
So many Hubs are over looked because the team don't think they are quality hubs. Most of us are inexperience writes who want to be told that our hubs are good. The Hubs I write about are things that have happen in the past and the feature that has once affect us all. By writing hubs it helps to gain knowledge and the ability to sat back and write a decent articles.
I am not a professional, I write because it's a great passion of mines if i get paid that would be awesome but if i don't it won't stop me from trying.
So many hubs are written with no understanding, I do think that mines tell a story.
