Happily married for many years as well.
Assigning points to women is helpful—particularly when assisting younger men in their journey through life.
I can think of several analogies—but they would be a bit ah controversial...lol.
I have a 17-year-old son who has already taken his first steps in the dating market, but...
I would not attempt to establish any sort of rating system for his use. Certainly not a rating system which supposedly has any sort of general applicability.
(Personal preferences play too much of a role.)
Rather, I would instead advise my son to keep an eye open for certain "deal-breakers."
Assuming you even have a group of "possibles" from which to choose, it should be a relatively simple task to "winnow" them down by applying a few, generally valid "knock-out" criteria.
The most-important exclusionary criteria would pertain to attributes which are not even visible (e.g., slootiness /illegitimate children, conceitedness, etc.) - and young men are essentially visual creatures (unfortunately).
Visible criteria would include obesity, massive dental braces, severe acne, etc.
But if I were a father advising my son on selecting a wife, physical attributes (as long as they don't preclude fertility) would be of diminished importance. (I know: Good luck trying to convince a strapping young man to "go" for the inconspicuous but serious, principled wall-flower!)
In my early years, I was probably what could be described as "hunky" or "hawt" (though I was socially awkward). Still, I had extremely strict standards concerning physical beauty. As a result, I "dated" only stunningly beautiful women.
I think that I would have "gotten more" out of "dating" and experienced more personal growth and maturation, if I had been less fixated on mere outward beauty.
Rating systems are probably okay for the dance floor, when trying to make a quick estimation from a group of total strangers, but if you are selecting from a group of people with whom you already have some at least slight acquaintanceship*, I would advise approaching the matter differently.
Regards,
*And, ideally, this would be the norm.
