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 Dual Berettas | Urban Shock’s range of 0.00–0.47. 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 | 0.0745 |
| Minimal Wear | 0.1100 | 0.2340 |
| Field-Tested | 0.2650 | 0.5638 |
| Well-Worn | 0.4150 | 0.8830 |
| Battle-Scarred | 0.4600 | 0.9787 |
“Not reachable” means Dual Berettas | Urban Shock’s own float range never enters that exterior band — no combination of inputs can produce it.
