In shooting there is always this haunting notion, this specter of “good enough”. As Claude Werner has pointed out over and over again untrained people have successfully defended themselves with firearms at rates that are impossible to ignore. That may seem an odd statement from a dude so into training to post on a blog about training but its true. I would contend if the problem doesn’t require skill than having skill won’t hurt, but if the problem does require skill then no amount of wishful thinking will do.

If you can shoot competitively then a simple shooting problem will offer you no challenge, but if you’ve only prepared for the easy problems a complex one will not stand still and allow you to catch up.
