I agree that it is pointless. MHXX would show ONLY that said dog has passed X amount of Master tests. I am putting a MH on my male and once he gets it he will not be running any more Master tests. After I graduated high school I didn't return to take the exit exam every year thereafter.
HRC has the 500 point club, the 1000, the 1500, etc. I need a couple more passes to have 500 points on my male. I'm doing this ONLY because I have never owned a jacket that costs $5,000!
However, to each his own, some individuals just like travelling all over the country and running hunt tests.
Although not a participant, I do agree with the others that if someone wants real bragging rights there is a venue just for that.
