The contract
10 inputs, all Restricted, all from Falchion Case. Concentrating every input in one case is what keeps your odds at 33.33% — mixing cases splits the probability across both pools and lowers your chance at SG 553 | Cyrex specifically.

Input float for each exterior
CS2 normalises float across a trade-up: each input’s float becomes a 0–1 position inside its own range, those are averaged, and the average is applied to SG 553 | Cyrex’s range of 0.00–1.00. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | 0.0350 | 0.0350 |
| Minimal Wear | 0.1100 | 0.1100 |
| Field-Tested | 0.2650 | 0.2650 |
| Well-Worn | 0.4150 | 0.4150 |
| Battle-Scarred | 0.7250 | 0.7250 |
“Not reachable” means SG 553 | Cyrex’s own float range never enters that exterior band — no combination of inputs can produce it.
What SG 553 | Cyrex is worth right now
Worth comparing against the contract cost above before you commit: buying the skin outright is frequently cheaper than rolling for it.

| Battle-Scarred | $4.38 | −$1.72 |
