Digweed is a genius. It is always a very bad example to take someone like him as an example of what the common man is capable of. Besides, do you really think he shoots his competitions with a random gun picked up of the shelf, which does not fit him?
As a language teacher, there were always 5% of pupils who would learn a language whatever method (or lack of) you used to teach them, they had a particular aptitude for language learning.
That was no excuse to have a department with poorly trained teachers who lacked a proper teaching methodology. If you did and pointed to the 5% who learned anyway as an excuse, the 95% of failures would have something to complain about; rightly.
Gun fit is simple - if the gun does not shoot to where you think it is pointing, you will miss. If it is too short, you will hit yourself in the face with your thumb, too long and you will struggle to mount it cleanly and it will be pointing across your body. Too much drop and you will shoot under things. Your get the picture.
Having said that, I do get frustrated when people look at a 100 year old gun and then give you a set of dimensions, all down to the extreme degree by a fitter quoting for a bespoke stock and expect you to be able to bent it to exactly what they think they need as if the wood is play dough! If it is basically correct and you practice enough, you can shoot well with a gun which is not theoretically perfect.
