I see the same thing with military and LEOs. Not many are really into guns and so many think since they shoot expert in qual, they're good shooters. The other issue is the common opinion among the tactical teds that a shooting competition does not replicate the stress of real combat, and to be competitive, you must do things that are not tactically prudent (i.e. standing in a doorway or window to hose a target array). There is an example of a very well-respected trainer down in Texas, a guy I would love to be able to learn from, who made a cautionary pro tip video about shooting plate racks, waiting for each one to fall rather than sweeping through the rack. My answer to someone with an observation like that is if you are fighting six "threats", giving a round to each before readdressing any particular one is probably more prudent than shooting one, assessing, and moving to the next, since people shot don't tend to drop instantly, and the rest of the threats remain fully functional.
As for replicating the stress of a real fight, nope. I'm dumb and have been perplexed and stressed by stages before, but nothing has held a candle to having an RPG round detonate right next to my HMMWV door and then looking for the guy who did it. However, I would submit that the pressure to perform rapid manipulation of your weapon and place fast, accurate hits under the pressure of time and knowing your peers are watching your every move, while not as rough as being in a fight for your life, is much more stressful than trying to perform a 6 second El Pres in a training course.
Sorry for the novel, but as a firearms trainer for the army's MP school who has been successful in getting exactly two of my fellow instructors out to a match in three years, this is another topic that hits close to home.
