Was 300 shots of Ulthera insufficient for treating the entire face?

I received 300 shots of Ulthera, and lately, while looking at the results, I suddenly became curious about something.

My biggest concerns were my jawline and facial sagging, so I was recommended 300 shots and received the treatment. However, considering the overall facial lifting, I am wondering if 300 shots might be too few. At the time, I was told it was sufficient for my skin condition, so I went ahead with it.

I don't think having a lot of shots is necessarily better with Ultherapy, but for those of you who have actually received 300 shots, which areas did you focus on?
