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 | 20,030 | 24,450 | 29,000 |
| 20 | 21,480 | 26,220 | 31,100 |
| 40 | 22,310 | 27,240 | 32,310 |
| 60 | 23,010 | 28,100 | 33,320 |
| 80 | 23,640 | 28,860 | 34,230 |
| 100 | 24,210 | 29,560 | 35,060 |
| 120 | 24,740 | 30,220 | 35,830 |
| 140 | 25,260 | 30,830 | 36,570 |
| 160 | 25,730 | 31,420 | 37,260 |

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.
