The problem with any scale is defining what the "numbers" mean. What is the difference between a 7 and an 8? Generally it is completely subjective.
In essence you have a numerical scale now: YES = 2, NO = 1. Look at the arguments on TER about inflation, subjectivity, etc. Make this a numerical scale and exactly the same thing will happen here.
I know it takes a little more effort, but the best "scale" is to take the time to write a good descriptive/explanatory narrative. That way you can say her face and welcoming personality were outstanding, the incall and certain activities were very good, other activities were OK, but her voice was scratchy and the faint smell of smoke distracted. That way the reader can assess whether for him, the negatives do or do not detract from the positives. Oh, that's right, we can (and should) do that in reviews now.
By the way, look at a lot of the reviews that do elaborate at times with more than "YES" or "NO."

If you are too lazy to write a solid review with HONEST information. Then do everyone a favor and just dont write the review. If you are going to write one you owe your fellow hobbyists and the girl in question a responsibility to write a solid, honest review. There is no need for a sliding scale because in the end its a simple yes or no.
