I have been watching the issf channel on you tube (yes I am an anorak!) and every shooter in the final of any event you care to watch stand side on (feet in line with the target). There must be a very good reason for this because it stands to reason that not every shooter has the same physiology. So the question is why do they all do it?

I have tried this method several times and it turns me into a novice each session so I go back to my comfortable 45 degree-ish stance and I go back to normal (better than novice!)
