February 17: $40/1.94=20.62 ~21 keys

Sales at 21, 26, 27, 38, 39

39 was dumped for 26 afterwards so excluding both those sales. 21 is also a lot lower than buyers: https://gladiator.tf/listings/6065b60644ff716584cdf4f3

27 wasn't lower than buyers at the time of the sale https://gladiator.tf/listings/6026dc93f4dca0591bc430f4

Gonna include 27 given a fair amount of lower sales happened. There are also only 3 higher buyers

Let's try 27-38
