Since we are going to the rule book a dog must carrry an overall average of 7 with an minimum average on blinds of 5.
Ch2 Section 1 "Qualifying score in senior and master Retriever Hunting
Tests, not only must a dog receive an overall average of
not less than seven (7.0) for the entire test, but it must also
receive separate, independent average scores of not less
than five (5.0) in each ability category related to
marking, as well as separate, independent average scores of not less
than five (5.0) in each ability category related to blinds."
The next paragraph is almost never used in my experience. Long waits for call backs!
"If, at any time during testing, a dog is graded zero (0)
by two Judges for the same ability, the dog cannot receive
a Qualifying score and the handler must be informed that
the dog cannot receive a Qualifying score."
But that is another discussion.
