Whats the point of rating attractiveness if beauty is subjective?

Not everyone finds the same features attractive, yes, there are people who are considered attractive by a large group of the opposite sex, but at the end of the day, there will be many people who also find them ugly or at least meh, it's a bit like musical taste, some like rock and others pop and with music bands, each one has its fans, a group of people who like their music, but there are many people who find that music bad or boring.
