Don't see why 70 should be in the range here when theres 2 sales ~85

another sale seems kinda too low well its oudated 1 year hat so idk

You should only be using clean sales as your proof here. At this value, the difference between duped and clean is considered significant (which your sales tend to corroborate).

So far we have:

https://backpack.tf/profiles/76561198043848031#!/compare/1490486400/1490659200 - 1:1 w/ Holy Grail Sorcery, was used to set the high end for the taunt, so it cannot be used again here

Leaves us with valid clean sales at 70, 82, & 85 (pure). No clean sellers that counter. I would count 70 as an outlier here, especially since it can sell for 85 in actual pure.
