-All non-mannco.store sales within the most recent 3 months should be included in your suggestion (for example, this sale of 22 keys after rounding down: https://backpack.tf/profiles/76561198358456673#!/compare/1779494400/1779753600)

-Instead of a range, one single value rounding to the nearest 1 key (in this case) should be used for each sale. The range is determined after accounting for all usable sales and current market’s buyers and unsolds.

-You need minis for complex trades involving items to prove how much they are valued. The Huntsman for example was dumped to scrap.tf for ~45 keys, which is closer to the value of an unmodified Strange ProKS Hunstman: https://backpack.tf/item/14898093593 . While the lowest sell order for a generic proKS weapon may be considered for use, other addons are not counted toward the item’s value in a suggestion unless there is a sale or buy order with a buyer for all of the specific addons.
