Hmmmm ..... interesting.
So rovers on same ticket were 1-3-7, so each combo in your multi would have 1-3-7 and one other runner, correct?
So no combination in your multi would have the second and third runners together ie numbers 8 & 9 togther in it.
So no collect?
Best you had on any single combination was First, Second, DH Fourth and First, Third, DH Fourth?
