So I've noticed when you send somebody a link to join chess.com and add them to your friends list, it shows some of your stats on the invite link thumbnail, on the browser version at least, and for me it shows what percentile of puzzle solvers I'm in. I don't know if this is true for everyone, I just know I've seen it before when I send friend links. I checked, and I can't find this percentile anywhere in my puzzle stats. Am I just not looking in the right spot, or is it not there? It's not in the spot that the player percentile usually is in stats, so if it's somewhere else I'd suggest moving it to match the other percentiles, and if it isn't a feature already I think it might be a good idea to add it in.
Also, I don't know if adding this is possible or not because the last time I saw it was before the puzzle rating inflation fix, but if it is possible, it might be a good feature to have, because there are some players, like me, who would find it useful.
Just a thought
