give us the proof, don't make us find the proof

Here's to help you even more: http://www.tf2outpost.com/search/84193039 No go do your own research!

That link is just a search page, doesn't even search the effect. Generally the point of a suggestion is that you do the hard investigating for everyone. If someone has to look themselves, they probably won't put the effort in.

I'll help you out here:

[url]http://www.tf2outpost.com/trade/8919885[/url] C/O 16 keys B/O 20 (6 day old trade)

[url]http://www.tf2outpost.com/trade/5217272[/url] C/O of Nuts n' Bolts Furious Fukaamigasa (15-19 keys) (4 days ago)

[url]http://www.tf2outpost.com/trade/9042890[/url] Denies offer of 16 keys, 20 keys minimum (1 day old trade)

[url]http://www.tf2outpost.com/trade/9052037[/url] B/O 19 keys, no offers (1 day old trade)

[url]http://www.tf2outpost.com/trade/9052084[/url] B/O 20 keys, no offers (1 day old trade)

Seems to me like the current range is fine. (B/O's don't determine the price, or else unusual prices would skyrocket)
