I don't feel that this would exclude me from discussing my observations on why it might be best for a woman to sit (or hover) when she pees.
I am not now, nor will I ever be DIR in even the loosest definition. DIR is a commitment to diving excellence which can be best described as a life style. I would hold JJ or GI3 up as two examples of DIR in the purest sense. I would say that the closer I come to that level of DIR, the better it will be for me.
Off the top of my head, DIR in its purest definition is about exercise, diet, physiology, gear and its configuration, skills and proficiency in them, situational awareness, standardization of technique and experience. It's the active pursuit of perfection in all aspects of diving.
From some of the attitudes reflected in prior posts, I am under the impression that some of you believe I should be DIR to discuss any aspect of DIR. I don't agree with that thinking. If the understanding is wrong, address that, but if it's correct, what difference does it make what the 'qualifications' of that person are?
