Every sig anchor × rank at A0. Sig levels in between interpolate smoothly (PCHIP) and round to the nearest 10 BHR — matching the in-game display.
| Sig | R3 | R4 | R5 |
|---|---|---|---|
| 0 | 20,250 | 24,740 | 29,320 |
| 20 | 21,930 | 26,790 | 31,750 |
| 40 | 22,780 | 27,830 | 32,980 |
| 60 | 23,490 | 28,700 | 34,020 |
| 80 | 24,130 | 29,480 | 34,940 |
| 100 | 24,710 | 30,200 | 35,780 |
| 120 | 25,260 | 30,860 | 36,570 |
| 140 | 25,770 | 31,490 | 37,320 |
| 160 | 26,260 | 32,090 | 38,030 |
| 180 | 26,730 | 32,660 | 38,710 |
| 200 | 27,180 | 33,210 | 39,360 |
BHR at each signature level by rank (non-ascendable — A0 only). The curve is concave — sig 0 → 100 captures roughly two-thirds of the gain from sig 0 → 200.
