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 R8 Revolver | Skull Crusher’s range of 0.25–0.80. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | — | not reachable |
| Minimal Wear | — | not reachable |
| Field-Tested | 0.3150 | 0.1182 |
| Well-Worn | 0.4150 | 0.3000 |
| Battle-Scarred | 0.6250 | 0.6818 |
“Not reachable” means R8 Revolver | Skull Crusher’s own float range never enters that exterior band — no combination of inputs can produce it.
