I have read much of this thread, with some amusement, I might add. Recall someone pressing ED for a defined judging std. There is a std I think that most judges follow. Here's an over-simplication. If you place a mark on your paper, as a judge, showing the place from which all dogs are required to start, then place a mark on your paper for the location of each bird thrown or shot, then draw straight lines between the start & the location where each mark falls, then you have a std of performance. Then trace the actual performance of each dog for each mark once the dog reaches the area of the fall (in the case of marks) & note the performance or hunt in and around the area of the falls for each dog before the dog retrieves the bird. For blinds, draw a straight line between the starting line and the blind location. For each dog running the blind note the deviation from the straight line. Then choose the winner as the dog with the least deviation from the straight lines, i.e., the smallest, shortest hunts (in the area of the falls as we are cautioned not to judge lines to the AOF by the governing rules) & the least deviation from the straight lines on the blinds. The evaluation is relative among the competing dogs with appropriate weight of the marks and blinds as per the governing rules for the particular stake being judged. Be consistent in judgement between the dogs & follow the governing rules.
And I think someone said it with even more simplification, the dog with the least lead on the paper wins....usually.
