https://backpack.tf/profiles/76561198195933333#!/compare/1620691200/1621555200 - Sold via buy order for 15 keys + ~0.5 keys in ref. Seems incomplete

Sales:

33, 34, 34, 35, 39, 40, 40, 42 and 46

Calling 33 low as it's below a handful of buyers, 34 can serve as a low-end here

Calling 46 high compared to other data points and sellers, this will help to even out the range also

Thanks =)
