How this list is built
The cheapest legal contract, worked through
ShowHide
Ten copies of UMP-45 | Indigo in Battle-Scarred at €1.01 each make the cheapest Consumer Grade contract here: €10.10 in, one Industrial Grade skin out. The cheapest Battle-Scarred copy sits at the worst float of its band, 0.8, which is 100 percent of the way up that skin's own range, and that position, not the raw float, is what maps into each outcome's range. At that float the outcomes land in Minimal Wear to Battle-Scarred.
Priced at those wears, 2 of the 4 outcomes we can quote net more than the €10.10 ticket after the venue's fee, and the rest net less. They run from €5.22 to €11.56.
That's the calculator's arithmetic on the cheapest listing, not a pick; price your own ten in the trade-up calculator.
Mixing in other collections

The ten inputs don't have to come from one collection: each input hands its own collection a tenth of the odds. Five Consumer Grade inputs from here and five from The Inferno Collection split the contract 50/50, so each of this collection's 4 outcomes drops to 12.50%, and The Inferno Collection's 2 outcomes share the other half.
