congrats on the great buck. Hope to get one like that sometime in the future.
I am not on official scorer as well, however when my dad scored his last goat the guy told him the third measurement had to be above the prong and that he could not get 3 below the prong no matter how high the prong was on the antelope. I am unsure if that is factual or not but just some info given from a scorer in Nevada.
