http://www.tf2outpost.com/trade/20082806 - smoking war pig (see: http://puu.sh/9Nni7/0063f7d0fa.png ) b/o was 7 buds. war pig price is outdated but considering it was quicksold for 4.5 in an hour here http://www.tf2outpost.com/trade/19718352 id say it's about right. 5.6*0.9=5

http://www.tf2outpost.com/trade/18807932 - beams noir (see: http://puu.sh/9Nni7/0063f7d0fa.png ) (seller didnt have a listing up) 4*0.9=3.6

http://www.tf2outpost.com/trade/19926733 - quicksold for 5 buds in 5 days. not entirely sure if that counts as a quicksale though

http://www.tf2outpost.com/trade/18804293 - hearts + ghosts tree (both duped) ( ghosts quicksold for a max http://www.tf2outpost.com/trade/20368311 here and sold pretty quick for 3.5 http://www.tf2outpost.com/trade/20602726 here and was offered a vivid kabuto [3.8] so ill value the ghosts at 3.8) (http://www.tf2outpost.com/trade/19506517 declined 3.5 on hearts, wants 4 [in comments] http://www.tf2outpost.com/trade/20206607 added 3 buds for a scorching (7 buds) so id say 3.5 is fair) 3.8+3.5=7.3 7.3*0.9=6.6

all the proof from last 3 months. 3.6 is clearly an outlier.
