Your 3.35 key sellers aren't even the mentioned price.

http://www.tf2outpost.com/trade/26716310 3.38, which rounds up to 3.4 keys

http://www.tf2outpost.com/trade/26672172 3 keys, 7 ref is 3.435, which would round down to 3.4 keys.

http://www.tf2outpost.com/trade/26650896 3.38, which rounds up to 3.4 keys

http://www.tf2outpost.com/trade/26711901 3 keys 7 ref, which is 3.4 keys rounded.

http://www.tf2outpost.com/trade/26707026 3 keys 6 ref, which is actually 3.375, which rounds too 3.4 keys.

Your sellers at 3.15 keys?

http://www.tf2outpost.com/trade/26726218 3 keys 3 ref, is 3.1875, which is rounded to 3.2

http://www.tf2outpost.com/trade/26078798 Same as above, 3.2 keys.

http://www.tf2outpost.com/trade/26670767 3 keys, 4 ref is 3.25 keys on the dot.

I'm not really sure where you came up with these numbers, but nothing here supports 3.35 keys. If anything, resuggesting with 3.25-3.4 keys would be a better range since you still have unsolds at 3.25 keys.

again, round to the nearest 1 dp please
