I went with the AK this time which was part of the problem and slowed me down. It shoots great but mag changes are a nightmare on the AK system. The AR platform is so much more comfortable and faster. But also a bit boring.
Anyway it's much less of a deal than you think, I don't have to do much, the body runs its routines on autopilot anyway. Like when you're driving a familiar route. If you consciously have to think what you are doing you'd be way too slow. So it's pretty much like a tulpa doesn't have to learn walking from scratch. We take over the body's muscle memory and give rough directions. Pretty much the same as you're doing.
There was a guy on the forum who said he practiced HEMA with his tupper as opponent in wonderland to ingrain movement sequences. A lot of professional athletes visualize themselves wonderland style, including fighting imaginary opponents. I can confirm this really works great once you got the hang of it.
Learning completely novel movements the body is unfamiliar with like dancing is an entirely different beast than routines though. We're both really bad and slow at this and need to break down movements into tiny chunks, then rehearse them until the body is able to unconsciously execute each of them, then chain them together. A Sharingan to instantly copy techniques would be tremendously useful. In fact there are people who can do this and copy complex movements they've only seen once or mirror them in real time. But that's definitely not us.
