This is a circular logic. My response to your statement that the ligament lengths prevent tunica stretching was that when the ligaments have been individually lengthened through BTC work, the tunica is unrestrained from stretching in the OTS position. This is not an assumption or an opinion, it is logical. The only way to disagree is if your statement is that the ligaments cannot be lengthened to the degree that the tunica will endure most of the stress. If this is your argument, that is another matter entirely.

The kind of fulcrums I’m talking about are full 90 degree angle around your thumb. That’s a much tighter radius then any RSDT. It does require the fulcrum point to move up and down the shaft though. The necessity of tunica stretching? I don’t believe that the tunica has any choice but to grow when it’s supporting structure, the ligs, are elongated.
1. You believe that the tunica cannot be stretched, yet you apply fulcrums to the tunica anyway? Why? You are right that the shorter radius will of course provide more stress. The reason the RSDT fulcrum is so useful is because it is not manual (easy to use) and because it has a DUAL fulcrum, not a single one, as with your finger. Further, the steepness of both fulcrums can be changed as one sees fit.
2. I did not mean to imply that you did not know of the existence of the RSDT fulcrum. What I meant was that you clearly have not used it (as you believe the tunica cannot take the majority of the stress). If you spend enough time hanging BTC (so that your ligaments are stretched enough that they will not take the majority of the stress with the RSDT), and then hang with a properly crafted RSDT fulcrum, further, with extensions on the Bib hanger (you probably have not encountered this, ironaddict is doing it for example), you will directly feel tunica fatigue. It is unavoidable. I have felt this fatigue, and it is what makes me sure that your assumption about tunica fatigue is incorrect.

Well, there are really no opinions here. Either the tunica can be stretched individually or not.
By the way, I do not mean to be argumentative. I enjoy your posts a lot and read them often, and respect you for the many useful ideas you have brought over the years. The reason I am discussing this is because I believe these discussions are useful.
I would suggest you build an RSDT fulcrum and attach extensions to it (I can provide a link with Bib’s instructions for the extensions, if you would like) and try it out. I suspect you will be surprised to learn how much the tunica can deform. Surely, it is harder to do than the ligaments (hence the dual fulcrum and extensions), but it is possible and an important source for gains, once ligament gains are exhausted.
I also believe that your bungee chord method is promising. The difference in strain could affect tissue deformation differently.
