I hate to tell you this JCN, but you're not discovering anything new. Use of dry-fire has been a training tool for a long time, by lots of different people and organizations. I've sustained myself for months at a time using just dry fire when working in foreign non-permissive environments where the discovery of my being armed would result in much greater ramifications than losing fractions of a second on a draw time at a match.
Here's some context for you: I don't know why you're trying to pick a fight with me on this, as I've never stated that dry-fire isn't a useful tool that helps people improve. So, I'm still not sure what you're trying to get out of this other than your typical autistic screeching.
It's not an assumption on my part. You post some pretty insane round counts all over the forum, either in an apparent bid to one-up the forum every chance possible or as a result of poorly developed social skills.
So, here you're attributing your claimed proficiency to dropping 20-40 minutes a day of TV, and not the tens of thousands of dollars of ammunition you shoot per year? That's either disingenuous on your part, or a "plot hole" in who you're trying to portray yourself as if you got ahead of yourself in posting how many rounds you actually shoot.
Speaking as someone who's on track to retire at 50 and bought a Porsche in cash last year, there's still no way I'd be able to replicate the amount of training you claim to do....and if I can't afford it, the average American earner sure as shit isn't going to get anywhere near it outside of some exceptional circumstances such as it being their job to shoot that much. That was the point of my post in an entirely unrelated, different thread from this one which for whatever bizarre JCN reason you've decided to cross-pollinate your bullshit with.
