21 seems low / 17 is below buyers

35 seems like a relatively common selling pt as there were other untraceable scrap.tf sales as well

26 was a buyer dump so we can exclude that as well

28 should be fine to include given the quantity of scrap.tf dumps

Taking 28 - 35 keys despite lower sellers c:
