To me, writing should be the determining factor only when the rest aren't viable. Into WOTW it was set up so that if needed the minor amount of points for writing, could be sort of the swing vote instead of the main. of course, judges would have their own styles I suppose because no matter tyw standard fare, we're all different and would see things differently. 

If the folks wanted a normalized grading scale, we could certainly endeavor to make one. Democracy and all.
