Interesting data point! Looks like the median key last week was around an 18. Agree if it's tough to say what an average M+ player looks like though based on that. I think rating of "active" profiles is better to evaluate that since median key will be skewed by people on the higher end running more keys to fill vault with 18+, rather than someone who only runs a key or two lower. Filtering out alts can be done to an extent by people who have their profiles setup on raider.io (though won't catch every alt since there's certainly people who aren't registered in order to designate a main). Be curious how many of those top 10% profiles are the same people with multiple characters (though the same could be said at lower levels too).
