Third sale ---- Not used

Tinge-Painted BS Harmburg (X) + Blizzardy Storm Prussian Pickelhaube (Y1) sold for duped Scorching Flames Pugilist's Protector (Y2)

http://backpack.tf/profiles/76561198095335435?time=1434697200 (June 19th vs 20th)

Mini on the Pugilist: Sold with 17 keys for a Pro. Ks. Scattergun (?)

http://backpack.tf/profiles/76561198133675785?time=1437634800 (July 23rd vs 24th)

Pro Ks. Scattergun on SCM around July 20th-26th: (126.5+110.77+115+108+120.46+111.12+103.63+115.22+106.98+119.89)/10= ~113.8$/~$2.47= ~46 keys

===> Y2= 46*0.9-17= 24.4= ~24 keys

Mini on the Pickelhaube: Couldn't find any. I found over 7 Pickels, but not a single valid sale. And even if there was one or two, should be used to update it.

Taking 13-14 keys range.

Lots of maths involved (i might have made a mistake), so criticism appreciated!

Actually, found one unsold that could be used as mini on the pickelhaube http://www.tf2outpost.com/trade/26781736 --- 20 keys (~1 week)

With that, on third sale: X=24-20= 4 keys ---- Big outlier, so it was invalid anyways, assuming the mini is somewhat correct.

On a side note, i think i will try to update the B.S. Pickelhaube tomorrow.

One more sale occurred involving a Sunbeams Cosa Nostra Cap, a HOUWAR, a Black Rose and a B.S. Harmburg. Of course, i can't use this sale since the Cosa and the HOUWAR are worth 100+ keys each.

http://backpack.tf/profiles/76561198090829296?time=1439794800 (Aug. 17th vs 18th)

Another sale: http://backpack.tf/profiles/76561198095335435?time=1440226800 (Aug 22nd vs 23rd)

B.S. Harmburg (?) + Cloud 9 Waxy Wayfinder (?) + Strange Blizzardy Storm Ground Control (?) for Scorching Flames Thirst Blood (82.5)

Thirst Blood and Ground Control are about to get outdated, but i will use current values to get an idea of the sale.

Ground Control is 35 keys + strangifier (~2-3 keys) ----- i will take 38 keys

Mini on Wayfinder: Sold with 16 keys and 1 key in sweets for Orbiting Planets Pyromancer's Mask (30.5) ------ Waxy = ~11 keys (???)

http://backpack.tf/profiles/76561198141389999?time=1439190000 (Aug 10th vs 11th)

That would put the Harmburg at ~29 keys. Even if the Waxy was worth 20 keys, 19 keys for the Harmburg seems like an outlier based on 13 and 14 keys sales. Probably would need minis for Thirst Blood and Ground Control, which would make this sale too complex.
