Judging by nature is subjective as much as one endeavors to use objectivity. The rule book as a guide states marking is of the utmost importance. Natural ability is important to improving the breeds. Training ability also is important. In a normal AA stake there are usually 2 marking tests and at least one blind to test training and control. I’ve judged with people that look at the marks for placements and use the blinds to separate like marks and other judges that weigh the blinds as either equal to a set of marks or some percentage thereof. I remember that Master judging evolved a scoring system to try to standardize. I realize that aside from the above there are many factors that lend into the final analysis at every trial style, perseverance, pleasing to the eye etc. but in general terms, how do you judge and separate like work at weekends end.
