How do you guys use it? I'll discuss a few.

One fixed point:
I think this is the most natural way and the way most people use it. You get a number between one and ten and fix it's purpose. 10 as the top woman you see on tv, 5 as the ugliest one you'd bang, and evaluate the others based on it.
Fellow numbersmiths might see a problem here though. lol

The TWO fixed points:
This is a working one. You'd fix two numbers. 10 for Scarlett Johansson, five for the worst one you'd bang. But the issue is, the fixed numbers and their meaning change radically the fitness of the women in it.

The engineer's habit:
A percentile. 0 is the ugliest girl ever seen, 10 is the the prettiest (or reserved for a unachievable standard). It works perfectly BUT the difference between 0 and 8 might as well as be the same between 9 and 9.1. Engineer's habit because we'll just say "yeah, that's how it works, better getting used to LOG scale because that's the proper way to talk 9s out of 10s man".

Engineer's correction:
A fixed number engulfs all the women that don't make the cut, whichever cut you use. 5. For the rest you use a percentile. This makes the scale usable but its fitness is also heavily dependent on the number and the cut criteria.
