I had a hair transplant 7 months ago at the crown area, what should I expect? (Photos)

I put down a photo a week after the surgery of 850 single, double, triple and four haired grafts,to see the density of the grafts, and a photo of complete 7 months …the transplant is supplemental of an old transplant 30% covered of the area,to have an opinion of what I should expect, some doctors say that 7th month is the middle of new hair growth, and some that I'm in 70-80% of the final result
