What…

24 is an obvious outlier. Excluding 24.

12 is also an outlier. Excluding 12.

Both sellers at 17 and 18 are 3 months old, however, there are many sales at and higher than those values (2 of which are marketplace.tf sales, and another being a full pure sale) , so it wouldn’t be a good idea to exclude them.

Going with the large range of 14-19.
