Picking up on something that was mentioned in the 'Adjusting Centre Shot' thread - ie
"....You can also aim with the string picture running through the sight pin as this eliminates any variablility in head position from shot to shot. (in practice I've never found this to make any significant difference - in my case the string is lined up with the inside of the sight ring so minimal practical difference)"
How critical or indicative of a problem is the actual position of the string picture? I have heard differing opinions on this, from 'doesn't matter, as long as its consistent' to 'should be dead centre, otherwise your head is all wrong', and even (from a county coach) 'if you have your stance and anchor correct, then you don't need a string picture' ( I suspect the last one is the most contentious

)
In my case, and I haven't been brave enough to mention it at the club, since I became aware of the string picture it has moved from the end of the sight pin ie far right of the riser (obviously inconsistent) and is now settled on the edge of the sight mounting 'wheel' - still right of the riser. I have quietly and consciously tried moving it to the riser window, but it feels most unnatural.
