I'm coming in without reading the previous thread, where I suspect there was some sort of heated discussion I'm glad I missed.
When I was paid with taxpayer dollars, I did plenty of training. My unit had a large budget and we used it to good effect. Most tools mentioned were used, save airsoft. We shot at paper, cardboard on static ranges, MOUT live fires, the whole shebang.
These days, when I provide my own training budget and range access is problematic, I train differently out of necessity. I'd like to go to gun schools on a regular basis, but that is not going to happen any time soon. (Then I, too, could drop gun school instructor names
)
Such drills as mentioned in the OP are handy, as is the timing of same. They are the next level of sophistication above single static targets. Introducing the time element is another level of sophistication. It is not the be-all, end-all of training one's self, but you gotta begin somewhere. Squawking about how it is not CQB live fire or force-on-force or something else it isn't makes as much sense as criticizing a hammer for not being a wrench.
Maybe the next step the author of the OP can take would be having the shooter move whilst engaging the targets. That can tell one about how precision & time of execution might be effected by the one's movement. There is a relationship between speed of shooter movement, precision of execution, and time required to execute. (And don't forget range to target.)
LL indicated means to introduce moving targets, which will add yet another level of sophistication. Other folks have suggested other ways that are likely within the means of normal folk. (RC cars & balloons, tires with center targets rolled down a slope, targets attached to a skid pulled by weights that are released by some means, etc.)
As for not timing the drills, I wonder how does one then quantify improvement? Oh, the usual target scoring can be used to measure precision of execution, but time required to execute is also of interest. I'd not dismiss it out of hand, especially when one has limited time & opportunity for any sort of firearms training. The time factor also increases the stress a bit.
As for remaining stationary, it is to be avoided if really bad things happen. Sometimes movement is problematic due to disability or circumstances. Learning to maximize one's chances from a static position has some worth. I recall Mas Ayoob had some interesting images & words in his Stressfire books on this. The most memorable were showing how one could pivot in place in a kneeling position, maybe on stairs (which would hamper movement), and still cover 360deg.
