One of the things about citing instructors to bolster an argument is that you can get X instructors and get X different arguments. Which one is right? Pincus says that if you are shooting tight groups that you are shooting too slowly? Okay, Clint Smith doesn't want you shooting any faster than getting good shots (palm-sized group). While Hackathorn believes in making good shots and striving toward good COM shots, he also believes any shots that hit the target are certainly better than shots that do not hit the target. As Pax noted, Farnam would have you zipper people. Wow, look at that. Four different instructors with four different approaches to marksmanship in self defense.
You can pick and choose a singular example such as the pharmacy incident and base your whole defense around it, but it is hardly a universal situation. It provides a singular situational example.
What was it Hackathorn said..."You should move, unless you shouldn't." Sometimes moving will put you in a less advantageous position or put noncombatants into a more dangerous situation.
And what did Clint Smith say..."I can't tell you what your self defense situation will be. Nobody can."
Sounds like Limnophile has worked out a plan that is based on his personal situation.
One of the things I really like about the Tueller drill is how unrealistic it is to the normal self defense situation that is likely to occur. In the Tueller drill, the defender has already decided s/he is going to shoot, but has not drawn a gun and has apparently decided to not draw a gun and not already be move to a better position. In fact, the defender has apparently decided that the best course of action is to not move until the attacker moves. It is just a race between the attacker covering the distance and the defender drawing (who may or may not be moving). In the real world, if you have already made the decision to shoot somebody at that range and don't have your gun out, you have likely made a serious mistake. If you have decided that you might have to shoot the person, haven't drawn, and you aren't already working your way to a better defensive position, you have likely made a mistake. So if you are in an actual Tueller situation, you have already screwed up.
You have to (1) recognize the threat, (2) draw and present, and (3) shoot as many times as necessary. AND--your attacker has to stop before striking you.
If you detect and start acting when the attacker is six yards away, and if he moves a five yards per second, that must all take place in 1.2 seconds--including the time for the attacker to be stopped.
The Tueller Drill is a drill and not a scenario. We should not treat it as a scenario because it is so blatantly unrealistic.
When you run the Tueller drill where the defender doesn't know s/he is going to be attacked in advance of the start of the drill that he doesn't know the person running towards him is an attacker, he loses every time. That is because the Tueller drill removes all that time from the OODA loop that normally would be lost. Being a quick draw is a great skill, but most people lose a LOT more critical time in the OOD part of the loop than the A in real life situations. Attackers usually don't start their running attacks from 21 feet or more when they do attack. They start from much closer. They don't first announce that they have a knife and give the defender the opportunity to go through the OOD portion of the loop first, then start the charge.
This is one of my favorite "Tueller Drill" fail examples. Paul J. Spencer was an arson suspect who led cops on a brief 4 mile high speed chase before wrecking. The video picks up the action from there. You can watch the clock counter in the lower right corner. It gives whole seconds. You need to know that this was a felony chase by multiple officers and that officers immediately drew guns BEFORE the attack started as per procedure in such a chase culmination.

He starts his attack, knife in hand, at 05:01:59 and disappears off camera at the end of 05:02:02/3 (clock doesn't show the 3 for some reason) and the defensive shooting doesn't start until 05:02:05. Officer Ron Dombkowski was stabbed/slashed in the face and Spencer was put down by 7 of 10 shots from officers Jeff Webb and Joe Fisher. Based on the distance estimated in the scene, Spencer undoubtedly covered his Tueller 21 before going off camera. According to PoliceOne, Spencer covered 22 feet before the stabbing started and was shot AFTER the officer was stabbed.

That the officers took the better part of 6 second to shoot Spencer is a testament to the fact that draw time (guns already drawn) was inconsequential here and yet Spencer still stabbed one target and that target FAILED to shoot Spencer.
Even in a situation where draw time was not an issue in this drill, the attacker managed to hit his mark. A good draw speed is great, but there is a WHOLE LOT more that goes into self defense shooting than the draw speed example of Tueller. Like the El Presidente, the Tueller Drill is a drill and not a scenario.
