Team Fortress 2
Counter-Strike: Global Offensive
Using sales that were less than a month old when I started making this suggestion (29/9)
Sold for $14.50 on marketplace.tf
http://manic.tf/keyprice/?at=2018-09-06 - $14.5 / $1.88 = 7.71 keys
Can’t find item history.
X = 7.5
Sold for 6 keys
X = 6
Sold for 5 keys + 20 ref
X = 5.5

Can almost guarantee it sold for 6 keys
Bot.tf shows a bot purchase at 4 keys:
but we can’t even see the item history. Even if it were usable, I’d exclude it due to it not being a common trading point, combined with the 2 buyers at 4+ keys
https://backpack.tf/item/4140978340 - 7 keys
https://backpack.tf/item/3321535315 - 8 keys
https://backpack.tf/item/4369484348 - 14 keys
https://backpack.tf/item/5428330274 - 15 keys
7.5 is too high given the unsold at 7 keys. Excluding 7.5.
Going with 5.5-6.
Sold for $12.99, $13, & $8.40 on marketplace
https://manic.tf/keyprice/?at=2018-10-13 - $12.99 / $1.78 = 7.30 keys
https://manic.tf/keyprice/?at=2018-10-15 - $13 / $1.77 = 7.34 keys
https://manic.tf/keyprice/?at=2018-10-16 - $8.4 / $1.77 = 4.75 keys
X = 7.5 (2x)
X = 5
The sales at 7.5 look like outliers especially given the sellers at 7 keys, and the sale at 5 keys would've gone to a marketplace buy order, so i'll exclude these sales.
