I think that skills in drawing quickly are good. Possible it just a bad term because of Hollywood but calling it quick draw invokes peoples sarcasm easily so let's call it drawing smoothly. Practicing smooth-draw conjures images of slow fire and is totally misleading in that because smoothness of draw is speed.
Weapon presentation is everything in my opinion. When Democracy fails it usually fails very fast you are likely to be being heavily stressed and distracted at the moment your inner voice says you better draw...if you have practiced this 5000 times or more then you will be more efficient at it and able to free up your attention to more critical issues at the moment. Does that make sense?
