Yeah, that's EXACTLY why I was asking. I'm coming across some puzzles that have 21% solve rates, and 1800 second average times, and then I just zoom right through them. It would be nice to know ahead of time that out of the (hypothetical) two people that have solved it, one found it extremely difficult, but the other found it really easy, you know?
