What do everyone think of adding, to the rules, a provision, which allows the mark throwers to call - a no bird if they feel that a bird has not landed in an area, completely in a different (extremely difficult) "area" to other previous birds.
In that vein, giving a dog a rerun, if for argument sake, it takes a certain amount of time for humans/other dogs to locate a sunken wet bird or bird that was determined (by the judge) impossible for a dog to locate.
