Looks like there's some new sales:

https://backpack.tf/profiles/76561198002391950#!/compare/1629590400/1629676800 - Sold for a Purple Energy Rebel Rouser + an Orbiting Planets Neckwear Headwear (13, indate)

The rebel rouser has very few other sales, I would use it there.

The person who paid 84 resold for 70 which is also way below current buyers, I would exclude 70 and make this 84 - 89.

Excluding 70 is also supported by the rebel sale and the more recent full-pure 89 key sale.
