Understanding is not the issue, time is. I am a mechanical engineer, and I work 80+ hours a week. I simply don't have the time available to reverse engineer my entire TJ frame. This is something that probably took 10 engineer's 2 years to do in the beginning. This is my third TJ, and instead of buying a lift kit, I want to design it this time. If no one has the information available, then I will have to do it myself. In the real world of engineering, models already exist on most existing products. With all the Jeep guru's out there, I just assume someone has already done the research, and are willing to share. At least I hope there are.
