Classies: https://gladiator.tf/listings/6244b44432a1e5fe965b4b23

Sellers above 5, buyers 2.47-2.77-3.03

(Buyers up to ~2.7 before also https://gladiator.tf/listings/6203f0e83f837918a2ed5173)

Given recent higher sales, and the higher market now, going to account for this by excluding some of the lower ~2.6 sales. The sale at 2.8 (provided by Blaze) is more recent than those. With only one buyer above 2.8, I think it works as a low end.

Taking 2.8-3.1 keys (still excluding cash sales as high, given lower sellers previously).
