In high stress situations most people lose fine motor control in their fingers which shooting to reset requires. Yesterday I was trying to program a garage door opener with very small buttons in 14 degree weather. I could move my fingers okay --- good enough for trigger slapping if I had been shooting, but lacked the dexterity and feeling for precise work, which shooting to reset requires. Most of us don't go shooting in very cold weather. It might be informative if we did.
