Too many 1-weapon sellers for there to be a scrap in the range.

(Substitute .05 ref for 1 weapon if you'd like)

http://www.tf2outpost.com/trade/10121123 19 UCs for 2 scrap, including sandvich, that's a lot less than a scrap.

Basically, way too many 1-weapon sellers for the .11 range to be necessary, and those are just unsold trades that showed up from outpost searches.
