the cotton is unpriced but he sold it for a searing pyromancer's, 5.4 after overpay, the terror is outdated but clearly this sale is likely to be nearer 7. not gonna use it due to only one sale for an outdated item on the cotton + outdated practictioner but it supports the range i'm choosing, i.e. it supports having 3 outliers grouped at 5.2-5.6 and the range being 6.3-6.8.

http://backpack.tf/item/2361804431

sold for tf logo pyromancer's + stormy waxy, ~6.5 with overpay but both outdated. as above, supporting the lower grouping of valid sales as outliers.

9. http://www.tf2outpost.com/trade/22665441#latest

sold for duped g.e. tree + 66 keys according to lucario, too old to use but again support for the lower sales being outliers.

okay, that's pretty much most of what i found. pretty confident that 6.3-6.8 is the best representation the data show us.
