Good basic article you posted, especially:
" Your dry practice should be conducted 3-5 times per week and last no more than 20 minutes. I often work through the scheduled session and repeat if any time remains. When conducting the training, I work at 50% or less speed, focusing more on consistent, perfect practice repetitions over speed"
IMHO, unless you have a laser like mental focus, 10 minutes is about all a "normal" person can focus on the fundamentals. I base this on my years of teaching CQB and shooting. Start with 10, if you seem fresh after 10, increase. Spend 10 minutes focusing on the front sight, 10 on trigger control, 10 on drawing from concealment, etc. The final sequence, place a SPENT cartridge on the barrel behind the front sight, squeeze the trigger without the case falling off. I often use dry fire practice as a form of meditation, withdrawing into a state which only consists of simple, perfect movements. ( Well, as much as I can:)))
BTW: Proper shooting of a handgun is a lot like martial arts, its been done before many times, but just "renamed for the present" . Its kind of sad, but I personally know several "brand name" firearms instructors and each have developed their own "defensive terms" . This instructor is using "access, withdraw, and drive". OK, what happened to drawing your weapon from the holster and "engaging" your target? "drive" (I guess) is a more PC term for civilians.
"Access" --get your hand on the gun
"withdraw"-get your gun out of the holster
"drive"--point it at the badguy.
Good Lord, I can see me screaming those commands out to some third world SF or police unit. LOL.
"Double or triple press"--shoot two or three shots
"Tap, Rap, Access"--clearing a jam or malfunction, slap the mag to make sure it is seated, rack the slide to eject or reload, look at the gun's loading port or top of the barrel to find the problem, all else fails, eject the mag, rack the slide several times, reload a fresh mag, assuming you are still in the fight:))
"Tactical reload"--I think you know this one but for the others: a tactical reload is done during a break in the fight, like finding new cover or running to cover and replacing a partially spent magazine with a full one, placing the one you reloaded back on your body. A lot of people teach to carry them in your hand after this technique, which in my opinion is shear madness. you cannot properly grip a handgun with a magazine in your hand.
