I believe you are spot on in your analysis and comparison. Hunt Tests are pass fail and Field Trials are Beauty Contests. I never did any AKC events because they were too far away, with the exception of my CGC all my titles were from the UKC. I don't remember the Blinds for HRCH being only 75 yards, I thought they were 100 yards...shorter for water. But it's been 12 years since I was running the circuit so I may be wrong.
I forgot about the triples, too! There was actually a quad in a Finished test last year . . . . my dog has a good memory, but I don't know if she could do that.
We were really excited about the Grand, and the whole club joined in to help. I was a banquet flunky, which meant stuffing 350 gimme bags with goodies, setting up tables and raffle prizes and the silent auction, and selling an incredible number of shirts and hats with the club logo on them! We had 3 whole tables full of shirts in all sizes, several hundred of them, and sold every last one. I was in charge of the Shirt Table, so I was very pleased with our performance. We sold the last shirt right before everybody sat down to the banquet - it was a 4X and it was hanging on the market, but a very large fellow came in and bought it and was highly pleased to get it!
