I am starting this note for you to report cases of when your rating acts weirdly. This applies to cases like:
Please provide further information, like the date (timeframe) that is involved, the question title (a link would be appreciated), if you answered the question correctly or wrongly, and the change in rating that you experienced. Please be as specific as you can, as that helps me trace down the issue. An example format is,
On April 10th, Maximize An Almost-Factorable Expression, I answered correctly in my second try, my Algebra rating dropped by 20 points.
From March 20 to March 30, I didn't do any Algebra problems, but my rating changed.
I will respond via email with an explanation, and I would ask that you reply back.
This is not for a discussion of how you want ratings to act.
