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 M4A1-S | Blood Tiger’s range of 0.00–0.30. 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 | 0.1167 |
| Minimal Wear | 0.1100 | 0.3667 |
| Field-Tested | 0.2250 | 0.7500 |
| Well-Worn | — | not reachable |
| Battle-Scarred | — | not reachable |
“Not reachable” means M4A1-S | Blood Tiger’s own float range never enters that exterior band — no combination of inputs can produce it.
