Your efforts and enthusiasm are appreciated, and it's fun to watch you fire balls into pockets at warp speed. But the video doesn't really show how you do it, so I can only comment on what you say about it.
If you start by lining up every shot the same way (center-to-center or center-to-edge), then obviously all the real aiming is done with the adjustment you make from there. You don't say how you adjust except that you "pivot" by some amount, and that amount is apparently chosen by you from experience - in other words, by feel. If you're using a system to tell you how much to pivot it isn't obvious what that system is.
At least in the narrow range of angles and speeds you showed, it works very well for you, but I don't know how you'd go about teaching it or adapting it to a wider range of speeds, angles and position play demands.
I saw that you like 14.1 and have some respectable runs. I can't imagine hitting shots in that game like you did in this video.
