Two things you said are so correct I have to comment. Stance, fighting stance perfect, secondly, if you move the way you showed the barrel goes across the horizon flat which is what you want. I watched another professional talk about leaning over to far and when you move your barrel it causes an arc to happen. Nice job.
... and if you could do that impressively fast, then I might be impressed, until then, "I'm throwing all that away" and using my peripheral vision like I always have.
Can't build a fighting stance if you've never learned how to fight. That's the problem with the generic ambiguous advice of "get into a fighting stance".
