Would 300 shots of Oligio be insufficient?

Lately, I feel like my jawline is becoming sagging, so I am looking into Oligio treatments. The cost of Thermage is a burden, so I have decided on Oligio, but I've noticed that people usually struggle to decide between the 300-shot and 600-shot packages. I am in my early 30s and don't have particularly chubby cheeks, so I am wondering if I will feel a noticeable improvement in overall skin elasticity or fine lines with just 300 shots.

For those of you who have actually received Oligio, what number of shots did you choose to be most satisfied with?
