Rules is rules
Should England win by 7 points, you score -17, the distance you were away from the correct spread. The Champion will be the individual with the highest aggregate score after all matches have been completed.
The winner will be the person with maximum points at the end of the group stages. In the event of a tie, the tiebreak question of who will win the F6NF will settle it. Should both then have the same answer, it will be settled by bare knuckle fisticuffs on a site yet to be nominated. Or by table quiz if preferred.
