Just to be clear, 'graduated hairline' doesn't refer to the shape of the hairline, it refers to the density.
A graduated hairline replicated the growing pattern of a natural hairline and prevents there being a thick wall of hair across the hairline.

'Recession' or a 'recessed hairline' refers to the shape/contour.
There are standard front contours for hairpieces such as A, AA , C, CC etc.

I think getting the template perfect or exactly right on your first order is an impossible challenge and I'm still tweaking mine 20 years later.
Have you considered ordering an inexpensive stock piece that you could play around with because this will give you a much better idea of what can be achieved, more than drawn lines on your head ever could.

And also remember, if you choose your hairline based upon someone else's head shape and haircut, and not your own features, you do risk it looking like someone else's hair on your head.

PS. Please note that the contours are not standardised and some companies use the same letters to indicate different shapes to those illustrated here.
