I don't like giving play-by-plays in my reviews, for the same reason that I don't like to tell movie spoliers to my friends.
I don't like rating SPs with numbers, because I don't like to label human beings.
However I still do it to help out fellow hobbyists.
To me: 7 is GND, 8 is pretty GND, 9 is a model, 10 is DDG. Everything below 6.5 is just ugly.
I feel like if an SP asked me after a session "How did I do?", I would be happy to give them pointers on how to improve.
However SPs never ask, and I'm not one to give advice when it's not asked for.
