https://backpack.tf/profiles/76561198419106750#!/compare/1610582400/1611014400 - The person who paid 97 dumped it for 73 Keys

https://gladiator.tf/listings/60007e4e74537ac98c3852bb - Samantha had a buy order of 73

As a result, I'd cut off 97 also, giving this a range of 83 - 96 Keys (83 can be included because of 2 instances where the buyer dumped for less).
