Q for 7sage: why did the section difficulty ratings change?

Just curious -- I noticed that all of the difficulty ratings seemed to adjust yesterday or the day before, with most of the sections now being rated significantly more difficult than they were before.

Thanks in advance for your response :)

    I checked it out, and it does look like that happened. That's strange - I'm not sure why. Thanks for bringing it up! I'm looking into it right now.

    Btw, I just rolled out changes to the grader:
    1. It's now significantly faster
    2. You are no longer required to enter at least 50 answers. Now it's easier to grade individual sections.

    Hey, I don't know what caused the difficulty ratings change, but I went and completely overhauled the section difficulty analysis so that it is faster, better distributed, and more accurate.

    Please check it out and let me know what you think!

    Just checked it out -- you've done some awesome work today! Super cool, and the ratings are back to being useful -- even moreso now.

    Thanks again :-)
