| pF | pAHC | ||
| Herod | 1758 | 19.87 | 25.13 |
| Eclipse | 1764 | 11.5 | 12.97 |
| St Simon | 1881 | 8.74 | 4.58 |

| Partner | 1718 | 3.62 | 12.97 |
| Roxana | 1718 | 2.28 | 2.49 |
| Total contribution | 80.40 | 82.18 | |
The final pair of columns shows the total average contribution of all 10 ancestors to the F and AHC coefficients. All values are expressed as a percentage of the total F or AHC value.
