I understand you, Pat,
This table is very sophisticated. So much, that person, who never played this game can easy judge maps. But for well experienced judge (we have) it may be too binding. Maybe they would like to have more "free hand".
On the other hand, now it is very easy to watch judge's thinking and compare different maps in different elements.
So, I am ok with both ways of rating. But If I was a judge, I would like to have rating system suggested by Pat.
