http://www.tf2outpost.com/trade/24112378 - 1 key: 1 day

http://www.tf2outpost.com/trade/23967793 - 1.08 keys: 1 week

http://www.tf2outpost.com/trade/23738024 - 1.35 keys: 3 weeks

TOTAL - 14 under 1.4k.

1 key is most likely a quicksell. There are 6 listings at 1.08 keys, so I round that up to 1.1 keys. 1.4 keys obviously doesn't sell as there's very little listings at that price. The 1.35 key listing hasn't been able to sell for 3 weeks, so kick that out of the range. The 1.38 key listing hasn't sold for at least 5 days, and probably won't sell soon, using the logic that the 1.35 key listing is hard to sell. So that kicks anything above 1.3 out of the range.

TL;DR - New range should be 1.1 keys to 1.3 keys.
