Bloggs, nice piccie. I should note that your piccie is not what I was asking about in the first instance. I can't possibly replicate your drawing but what I've observed most often is the aircraft following the guidance until the nosewheel is on the runway then doing a sharp (20 degrees or so) turn in the opposite direction to the take off direction and then doing a sharp (full lock) 110 degrees turn back the other way. I agree that the drawing you illustrate would enable less tyre scrub but that ain't what most of these guys are doing.
