the rating scale stuff reminds me of the recent meme girl who is "Looking for a man in Finance, Trust Fund, 6`5, Blue Eyes." a stats podcast i listen to broke it down, part by part, and said there might be 7 men in the whole UK who fit that description. who then might not like her back, particularly considering the moneygrubber vibe.
i say this because rating scale crap resonates like that. you are looking for people you enjoy hanging with, who you find attractive. putting a darned score on it only messes up that process, and artificially shrinks your dating pool. which is particularly dumb when you can't even get a date.
my suggestion to people in your place is broaden your interests. some athletes are akin to olympic gymnasts who train every day. they go to class, practice, hang out with guys, home. they don't have a lot to say beyond their sports, because that's where all their time goes. they may be interesting people but only after a while around them. they are almost autistic that way. if you want out of that, explore some side interests. hobbies, art, music, travel. broaden yourself beyond a jock. you then may meet women with those side interests. or those side interests may make you more interesting to be around. work on you.
failing that, jocks tend to understand each other and have common interests and obsessions.
last point, but the "scale" tends to reflect an abstracted idea of women by people not getting much. in the sense of treating them as pieces of meat and sex objects. in the sense of often reflecting conventional social ideas of beauty. just start talking to girls. any girl. get to know people. you may find if you actually talk to them, that in reality your ideas of what is attractive are different from what your fashion-driven scale said. or that you love that girl you were about to dismiss with a 7. that having met her, she's your 10.
last last point but a lot of these incels are almost like you're owed something or someone. it's oddly at odds with their own often-libertarian politics, which should suggest they can do whatever but so can the females. so work on you, become a more interesting human, and just talk to people, including plenty of girls. if you engage them rather than put them on a scale you might find your chances go up.
