7 month old price

http://www.tf2outpost.com/trade/16394502 sold for PE beak(clean,9) + GE goggles(2.3) + max(2.2) = 13.5

3 month old sale, but http://backpack.tf/vote/id/526f4b744cd7b823418b456e sold for terror watt lucha(4.2) + orbiting fire brainiac(3) + bills(.3), histories match up on that stuff though = 7.5

why do i feel that 7.5 is an outlier? the lucha price was very recently dropped, and at the time would have been 7.6 after overpay.

the guy also had an offer of miami wraith which is like 9 after overpay

mainly been crabbed otherwise
