How many grafts do I need? (photo)

I have had 3 consultations and each one told me that I needed a different number of grafts. One doctor quoted 4000 grafts, another 3500 grafts and a third 3000 grafts. It is very confusing. My hair is a medium weight hair (I know you always ask) so I am asking you what you think I need for grafts. Too many doctors or clinics push up the number of grafts well beyond what you need.
