Link 3: http://www.tf2outpost.com/trade/9553915 - duplicated, not considering for price check.

Link 4: http://www.tf2outpost.com/trade/8904209 - Not much worthy offers, mostly on other unusuals. Not considering.

Link 5: http://www.tf2outpost.com/trade/9577279 - Very fresh, opened 12 hours ago, no offers yet.

In a conclusion owners receive offers of 6 pure buds and consider only 7, low value can be 7. And as long as unusual offers touch 7.0 - 7.5 and there is a "possible" pure offer of 8 buds, 7.5 seems fine for the high value.
