I'd say that these are pretty representative numbers, if a bit skewed towards meta because these are the top 50 groups. Tack on maybe 3 or 4% to MCH and RPR and you'd have accurate numbers (or as close to accurate as you can get.)

PF in NA is pretty much where you'll find a majority of raiders, most people aren't up to par/don't have the confidence to join a static.
