Classies are so tight that Gladiator.tf stats should be fine here

Classies : https://imgur.com/UCh9rDW

4 sellers at 53.22 ref and others below 1 key, buyers up to 47 ref

1 key is an outlier here. 1 buyer at 47 ref isn't enough to exclude 2 sales at 46 ref. 54.77 ref isn't too far apart from 53.22 ref so going with 46-54.77 ref
