" Just be careful what you are practicing " Right on, as both a competitor and what we used to call " marshal artist with a gun "
The original practical shooting was more prone to training, Hot range, which meant you were loaded and holstered when you got on the range, you firearm was loaded until the end of the night. We did lots of skill sets, Weak hand shooting, drawing, reloading, strong hand only as well, shooting from awkward positions, including on your back over your feet, shooting from moving vehicles, or at moving targets, inside vehicles, over walls, swinging on ropes etc... I have no doubt this helped me. We also shot ( secret ) stages in the dark, grab your flashlight and go find bad guys, don't shoot the innocent, don't talk to anybody after you go through as to give them an advantage. When I became a match director for our home grown tactical/practical match, My goal was to make each stage stress a skill, fast and furious, low round count, reloading, cover and concealment, long range pistol shots, out to 100 yards, and usually a secret stage, you get a scenario, but no look at the stage design. We might mock a building, or you would negotiate paths, that provided targets as you came to them, We used the photographic targets, that allow you to put an insert into the hand of the target, gun, knife, cell phone, badge, drill motor, cigs etc... I would have stages holding a sack that was weighted and it was your child, to protect as you go through the stage. Many shooters did not like it, low round count = less fun, skills they did not possess like shooting 50 to 100 yrds. The martial artist crowd loved it, I even made a target like Thunder Ranch uses, but not as expensive, and ipsc target with balloons on the back side where you cannot see them but placed in strategic places, head, chest and pelvis, you shoot until the target drops, I hate to tell you how many competitors ran out of ammo on those stages, the hits still have to be on point. We even put a water sprayer that was remote controlled, so if you exposed yourself too far, you would get wet, and penalized. The range officer could even give a shooter " style points " if he or she made and exceptional solution. We ran our matches with what we called " do right rules "
if your trying to game it, and it is out of context, you lose points or gain time, completely arbitrary, very little discussion if you f up.
A suggestion to other match or stage designers, I did one stage that I think was really a good idea, and it was an exposure drill, par times of 2 seconds, allowed I think .15 second to respond to the stop buzzer, shooter starts behind cover with gun in hand, ready to fire, he or she only gets 2 seconds to expose and fire, then has to go back to cover and come out the next from a different spot of cover, repeat until all targets are down, and add up the time at the end. Would have been better if we could have moved away from the targets to create distance, but retreating ( moving backwards ) is not allowed on our range. Best shooting I have ever done in my life, I won't say what I did, but man I wished I had it on video.

The point is we tried to make it challenging, not a target shoot, our range will not allow 75% of what we could do in the old days, and I'm not griping, but that is what made me a better shooter, we did not have a rule book, just a scenario and your ability to solve it. I learned a lot from other shooters solutions as well, just like I do when I watch the BD shows. A smart man learns from his mistakes, a wise man learns from other peoples mistakes.
I think both Pincus and Janich bring a passion and intensity, that is rare, and Michael B, finds other instructors who seem to share a lot the same strengths.
Something Rob said is what is strongest, " when you are truly startled " Thank God, every time I have been truly startled, my reactions have been instant, and so far I have survived, there are a few men out there that wished they had not startled me, I am usually a slow twitch guy, not so when scared. They say you are one or the other, my fast twitch fu, scares me. It takes an exceptional competition event to reveal this response, wisely so I would offer. Water boarding comes to mind as a real response maker, in a controlled environment, and no I don't want to try it, kudos to you warriors that did it.
