OOM: I think you exaggerate the method of selection that WIY uses. He doesn’t sound like he dates the one supermodel out of a 1000 girls. There are certain girls a person wouldn’t wanna date on first looks, and that may be figured out many times from a picture. He may even whittle down half his list like that.
At the end of the day, he has a big enough of selection that he can rely on G-d that there will be at least one girl with the right personality and Hashkafos out of the remaining girls.
