Let's end this for once and for all.

Credits to whoever contributed the first four sales:

Sale #1

Sold with ~0.5 Keys in Robo Parts for a Magnetic Hat Protector Universal Translator(47.5 Keys)(47 Keys total, Outlier)

http://backpack.tf/profiles/76561198011061869#!/compare/1464048000/1464134400

The Translator needs a drop, this could contribute on that when the time comes I guess.

Sale #2

Sold for a Smoking Salty Dog(43 Keys)

The Spec KS Kit was not involved.

And now for the sales no one wanted to touch:

Sale #5

Sold with ~10 Keys in Sweets for a Blizzardy Storm Galvanized Gibus(55 Keys)(45 Keys total, Outlier)

http://backpack.tf/profiles/76561198107223339#!/compare/1466208000/1466294400

Should be used for the gibus really, it's going to be outdated soon.

Sale #6

Sold for a Steaming Pirate Bandana(19.5 Keys, rounding to 20) and an Orbiting Fire Tavish Degroot Experience(13 Keys)(33 Keys total)

http://backpack.tf/profiles/76561198285293652#!/compare/1466294400/1466380800

Sale #7

Sold for an Orbiting Planets Brown Bomber(21 Keys) and ~9 Keys in Sweets(30 Keys total, Outlier)

http://backpack.tf/profiles/76561198136456369#!/compare/1466812800/1466899200

Sale #8

Sold for an Electrostatic Company Man(31 Keys) and ~4 Keys in Sweets(35 Keys total)

http://backpack.tf/profiles/76561198183681006#!/compare/1466640000/1466726400

Sales at 30, 33, 35, 37, 43, 43, 45 and 47. Made 30 a low outlier and 45-47 high outliers for their own reasons. 33-43 Keys should be fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
