I understand it is scored total cumulative number. That said if anyone makes an effort to write a story I would say the effort made regardless of one reading it likes the story or not is worth at least 1 or 2 points minimum. Think of how any author would feel if someone said their story was worth nothing. I, for one, could never be that mean.
I missed last fall's Challenge for various reasons (the good one was being on a Caribbean cruise during part of it), but I believe that the lowest rating I've ever given a Challenge entry is a "4."
Most of my ratings tend to be in the "6-to-8" range, as I recall...
