The contract
10 inputs, all Mil-Spec, all from Horizon Case. Concentrating every input in one case is what keeps your odds at 20% — mixing cases splits the probability across both pools and lowers your chance at G3SG1 | High Seas 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 G3SG1 | High Seas’s range of 0.00–0.70. 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 | 0.0500 |
| Minimal Wear | 0.1100 | 0.1571 |
| Field-Tested | 0.2650 | 0.3786 |
| Well-Worn | 0.4150 | 0.5929 |
| Battle-Scarred | 0.5750 | 0.8214 |
“Not reachable” means G3SG1 | High Seas’s own float range never enters that exterior band — no combination of inputs can produce it.
What G3SG1 | High Seas is worth right now
