How Do You Know When You Have Maxed The Suspensory Ligament

Starting to hang,I have been light hanging a lot and now have worked my way up to 2 1\2 pounds . Been doing PE for about 3 years,sometimes on the weekends when off work I hang 4 to 6 hours at 9 to14 oz .I use a sock hanger with weighted caps.My question is how do you know when you have maxed your suspensory ligament? Any help would be greatly appreciated.

Sorry meant to suspensory ligament.

I always went by the feel. I would increase weight if I feel I can withstand new pressure. So, I was more concerned with measurements of my penis (I.e. If I grow or feel a good stretch, I keep the weight)
Eventually, your penis will hang much lower than before. And you could feel, with your fingers, a distance between a penis and pubic bone - a hole or a small pit between penis and pubic bone.

Yeah I understand,thanks for the good information.I have been hanging about 7 months now and I usually don’t go up in weight but every 2to 3weeks a 1/2 pound,I do 4 20min sets then on weekends I do anywhere from 5 to6 split sets I’m at 9pounds right now and don’t want to go to much over 10 .I also use silicone sleeve for ads.Thanks for the information every bit helps.
