Whilst browsing for 10M AP related things, I found this picture >>>CLICKY<<< of a young lady shooting her Steyr

What immediately struck me was her 'upward bent arm technique'

The competitor in the middle seems to be aiming in a rather more relaxed, or less strained method, while the furthest shooter seems to be using a fairly normal looking technique.

So how do you aim your pistol and what factors determine your aiming technique?

These fellows seem to use a fairly relaxed position, with the head not really too close to the top of the arm, and the arm looking not entirely 'locked-out'.
