Stop in for a cup of coffee

Hey Zman have you ever went to any courses led by Rob Pincus? He has developed a pistoleros system. I went thru one of the classes this last weekend in adverse conditions. Numb hands dumping mags in mud puddles fishing them out of cold water reload and get back in the fight. At the end had to literally do math equations and tricky word problems in your head to figure out which targets to engage. All targets had numbers and letters spray painted all over them. As you moved around obstacles instructor would shout out a problem the answer was on at least one target. Example: what is x plus one? Answer Z, find target with Z on it and engage. I blew a simple stage at one point. My question was a math problem of 21 minus 17 equals what? I found the target with the 4 on it blistered it and reholstered. I was then promptly informed I was dead as there was another target with the word four on it in alpha characters. I only engaged one bad guy and there were clearly multiple targets! Arghh! Fun class but holy smokes.
