#1 sale

http://www.tf2outpost.com/trade/23940852

Sold for Max Head (couldn't find the level of it in bp's histories, buyer just got it before the trade, and seller sold it right after the trade).

After tracing the buds in the seller's bp ( http://backpack.tf/item/184934731 http://backpack.tf/item/93306184 http://backpack.tf/item/93502024 ), it led me to "sazed" who was a buyer of a clean Max non level 1/7 http://www.tf2outpost.com/trade/24139699 when the sale occured

Assuming that the Runner was sold for a clean Max non-level 1 -> 3.3 buds low-end

#2 sale

Offered with 1 bud for a clean Beams Batter Helm (outdated) -> no overpay : 4.8-1 = 3.8 buds high-end

Sold for clean lvl 89 Max + 17 keys -> 4.5 buds pure

#3 sale (used as support proof cuz estimated with SCM sales)

http://backpack.tf/profiles/76561198110975329?time=1422259200 -> http://backpack.tf/profiles/76561198110975329?time=1422345600

Sold for pro Aussie Scattergun + 2 Naughty keys

Average sales of Pro Aussies Scattergun on SCM ~ 120€ on the 25th of January -> 120/2.15 = 56 keys (49 keys without fees)

-> (3.5 - 4 buds)*0.9 + 0.2 buds -> 3.4 - 3.8 buds, right in the suggested range.

Any comments are welcome.
