I know people learn differently and maybe it's just me, but I never bothered to look up a trainer or read a guide or anything. I learned by doing it, flying until I got it right. It was all instinct for me, doing what I can to get on the other guy's six. I was doing moves that I didn't know what they were called until long after when I actually bothered to read.
Do I need improvement/can improve? Sure, everyone can. But to get to a point where you can consistently land kills is the most important, and IMO, 80% of it is instinct and 20% is training for the average guy.
Myself was more like 95% instinct and 5% training. I had no one to teach me (played H2H when I first started for a year), I read almost nothing about ACM and gunnery until long after I realized I was already doing it, and it wasn't until last year that I picked a plane and focused on it (109K4). Every now and then I'll ask to DA someone and it helps me more than can you imagine. You can see how you compare to all kinds of players and work on it until you it right (shoot someone down).
TL;DR: Flying is mainly instinct and DA matches was how I learned. IMO, forget the rule book and guides, pick an opponent who is willing, fly against him and see how fast you can get on his 6 and shoot him down. It's all instinct.
I find this an interesting take on things! I would like to comment on some of it though.
When learning a new skill a person goes through a couple of stages,the first being the basics of W5{who, what,where,etc} then you get to the cognitive stage where you know the basics but still must think about what you have to do.Then with time, experience and many hours of repetitive practice you eventually get to the instinctive stage.
At this stage you no longer have to think what to do next you just do it,pare and counter,he reaches in you throw the uppercut without think and it lands because of all the time and practice you've done you know that will work. Same with flying,fighting,golf any sport or activity,it's just the way we learn.
I've trained people over the years,not just in AH but in other endevors such as boxing,flyfishing and TKD.
Every single person went through these stages and hopefully at 1 point a light went on and things clicked,thats when it becomes instinctive.
YMMV.
