I ended up doing about 4000 dry fire draws in a week to build the muscle memory to shift my grip position
Let's do the math, shall we?
A week has 24 x 7 = 168 hours. In order to do 4000 draws in a week you'd have to do 24 draws every hour. Non-fucking-stop. Every 2.5 minutes, draw and reholster.
But wait, don't you have to sleep? Sure, assume 6 hrs of sleep every day. Now your week has only 126 hours so you have to do 32 draws an hour. One draw every minute and 52 seconds. Every fucking waking hour.
But wait, now don't you have a job to do? Sure do. Now your week has 86 available hours and you have to do 47 draws an hour. That's 47 draws every hour that you're not working or sleeping. One draw every minute and 17 seconds of your total free time.
And we haven't even factored in the hours spent in the car, doing errands and chores, and even eating and taking a shit. Let's just say that eats up 4 hrs every week day and 2 hrs Sat and Sun. That now leaves you with 6 hours per weekday 16 hrs per weekend day to do this fuckery so now you look like the energizer bunny shoving your gun in and out of the holster every 38 seconds for six hours straight on weekdays and the rest on the weekend.
What a crock of shit
