How many shots of Shurink treatment are generally required for high satisfaction?

I am looking into getting Shurink for the first time, but I am having trouble deciding because the number of shots recommended varies from clinic to clinic. Some places say 300 shots are sufficient, while others recommend 600 or even 900 shots or more. I am wondering if the more shots there are, the better the results, or if it is more important to receive treatment tailored to my facial condition.

For those of you who have actually received the Shurink treatment, how many shots did you have? I am curious if you were satisfied with the jawline definition, facial elasticity, and lifting effects with that number of shots. I would also like to hear stories from those who had to receive a re-treatment because the initial number of shots was insufficient, or conversely, those who regretted receiving too many shots.

I am curious if the recommended number of shots varies depending on age or the degree of skin sagging, and I would appreciate your advice on how many shots are appropriate to start with for a first-timer. It would also be very helpful if you could share your satisfaction level relative to the cost.
