DLD,
Well, you are partially correct. The goal is to get the ligs fully stretched out (an LOT of 6:00), meaning that when you're doing tunica work, the ligs would be too long to take stress away from the tunica. I gave this example just the other day. Let's say you are doing DLD Blasters. If your ligs are high up, at the front face of your pubic bone, then the stress from the Blaster will be divided by three tissues: the outer tunica, the susp. ligs, and patially the part of the inner shaft which is held up by the susp. ligs. So the stress is being divided, and therefore each of the tissues receive a different force. In this example, if the ligs are tight, then they would take a much greater percentage of the overall force. This is where LOT come in. If you stretch out those susp. ligs first, enough so that they are not interfering with the force of the Blasters, then the outer shaft and the entire inner tunica take the load, and gains can be realized much faster, more efficiently. Once your ligs are out of the way, your target tissue would be the tunica. As you make tunica gains, the shaft gets longer, and the ligs follow the length gained on the shaft, and therefore become tight again, raising your LOT once again. And so you would switch to dedicated lig work, such as BTC, to stretch them out again. Thus, your LOT tells you what tissues you should be focusing on, either ligs or tunica, so that gains can be made more efficiently, rather than taking the shotgun approach, trying to deform all the tissues at the same time, which results in very, very, very slow gains. The Blasters were just an example. The point is, if the ligs are long enough, your inner shaft will take more of the stress, resulting in more micro damage along the ENTIRE shaft (as opposed to just the outer shaft and ligs), which will bring better gains.
The tighter the ligs, the higher the LOT, the more potential for gains from lig stretch. That is it.
