For what it is worth...
I am not the person who has been low-balling you. If I have left a comment with praise you got a good score, and if I left comments with moderate criticism, you got a decent score from me. I gave out no ratings below 5 and I gave my very first rating of 10, this year.
I gave out more than a few 9s, and a lot of 6, 7, or 8 ratings, this year. But I do not believe in punitive or retaliatory scoring. I use a points system based on a checklist of my own design. I reward for quality and proper rigor. Confusing or confused essays get a lower score.
If you need to retaliate, or find a scapegoat, please look elsewhere for your detractors. I have been getting hit by people giving me low ratings and making no comments. Please don't imagine that I would treat others that way.

Jonathan
