I guess there probably is/can be differences from one person`s head to another.... the further down you go away from the occipital bone and onto the nape area, the skin there moves/stretches a lot and may give you issues with your bond not holding so good there...you`ll have to use your best judgement ..the trade-off between not having the hair very long there and the need to avoid the area/skin prone to most movement. It`s one of the downsides of Fullcaps as opposed to toppers...but then toppers have the colour and blending-in issues which Fullcaps don`t, all part of the fun! I`m sure you`ll nail it anyway....will try to get that pic on tomorrow..tried today with no joy and then I had to go out.
