Don't normally do 3rd gens, but I have my reasons. Maybe this will bump my contributor badge up to the next rank! :D

Sale 1: http://www.tf2outpost.com/trade/25426455 (Item: http://backpack.tf/item/2204567467 ) Basing the sale off of individual item histories since backpack histories aren't reliable due to the quick turnaround of the TC.

Appears to have sold for http://backpack.tf/item/2037189785 and http://backpack.tf/item/730188451 . 9+4.35 times .9= 12.015, rounding to 12.

Supporting proof: http://www.tf2outpost.com/trade/25033266 -Unsold at 13 with few offers despite being up for over a month

http://www.tf2outpost.com/trade/22128277 - Unidentifiable, but had B/O of 13

Other sales were too complex to use, clear outliers, quicksales, or completely untracable.

As usual, if there is anything wrong with this suggestion please tell me and I will try to fix it! Thanks in advance and have a nice day :)
