Yeah to me its about the height vs the length and the density of the piece. It has to be symmetrical. You can have angular temple recession as long as the distance is not extreme. When I designed my temple flaps I looked at numerous pics of people with real hair and studied different hairlines and temple points. The worst is what you are saying. When its high density, and too low of a forehead matched into receceeding side hair or hair that is way too wide. Total giveaway.
