Thanks; at this point I'm taking a couple months off - August and September - to get re-settled, so maybe I'll have more perspective come fall. But yeah, if you're going to have rating systems, you shouldn't futz with them if the writer is generally not bullshitting.
Though the point is taken that in my case, I tend to save the best stuff for a couple of spaces, so I could be shifting the bias. Maybe I should start reviewing lame-o CDs on that site too.
