I believe the technique may look time consuming when wearing OWB holsters and standing at the open range, BUT it was designed to to be a very efficient draw and presentation in a variety of cluttered environments and retain maximum control of the pistol.
Sure, it may be a lot more work than a pull and shoot if they threat is only 3 ft away. So if the threat is 20 ft away do you change your draw? I think the intent is to have one fairly simple draw that works for a variety of distances and circumstances and you only practice one method very well. It may not be the fastest at point blank range but it is probably more controlled and accurate at various distances and environments.
