I posted a somewhat detailed description of the test at www.pointinglabs.com in a thread titled, "Who here also runs in NAHRA?"

I think the portion of the test that put a lot of dogs out was the Water Blind Retrieve. Your dog was the Honor Dog (HD) after making all of the Water Retrieves. The HD was 5 yards to the left of the Working Dog (WD) - both dogs were right at the shore edge.

A bird was launched at about 80 - 90 yards on the left (a line to this mark took the dog only about 3' out into the edge of the water. The dog would go through 50 yards of water and then the rest was on land. The 2nd bird was launched straight across the pond = 90 yards of water and 10 yards of land (kind of a gimme) -- BUT the 3rd bird was an "over the shoulder - from behind" and splashed down only 10 yards directly in front of the HD. The WD made this retrieve, and of course this was teh bird that all dogs picked up first. When the WD was sent on the 2nd retrieve (first bird down), the HD was excused. There were a few dogs that broke in this situation and were out of the game. The WD picked up all 3 marks and then the Blind was last.

The Water Blind : The bird was placed 25 yards downwind to the right of the first bird down. A lot of dogs couldn't be handled off the scent from the area of the mark -&- this is where a lot of them went out.
