People tend to forget that playing guitar, if you look at it from a physiological stand point, is a succession of muscle contraction and release.
To be able to reach that level you're muscles needs practice. Just like a track runner, just like any other physical task. The muscles are just smaller. This is why I always tell the students to watch out for hand pains.
You're knowledge makes you understand music probably better than a lot guitar player. The problem is, you don`t need to understand music to appreciate it. Eventho you have studied the guitar indepth, to alot of people what you're saying won't matter. This is why the speed debate will forever exist. I'm not saying everyone should stop trying to explain it... just that it's going to be a long road before you succeed.
There's probably has many thread trying to explain it as there are thread about the subject itself lol
