Doggone it Dave. You're making this tough. Marking is of primary importance. Sez so right in the book. The book might give primary importance to the marks but it doesn't say the blinds carry no importance or are pass/fail.
I can't give lots of weight to the flyer because of lots of varying falls. They just aren't the same mark for all dogs so as long as the dog picks them up I don't weigh the flyer to heavily. I didn't say the flyer carries no weight.
I want to see the work! 10 judges could see the same work and 5 could go with one dog and 5 could go with the other dog. I know how hard it is and what kind of standards have to be maintained to train for excellent blinds; so I might be a little more prejudiced towards rating blinds higher than someone else.
