Sale 26)

https://backpack.tf/profiles/76561198311773504#!/compare/1559952000/1560038400 - Bulky

Sales we have are:

18, 19, 20, 20, 20, 21, 21, 22, 22 and 24

Knocking out 24 of the range to tighten it, sellers at below and every other data point is beneath it

Calling 18 low as it can quicksell for 19/20 Keys easily, also helps neaten the range whilst keeping the mid-point pretty much the same

Thanks =)
