I can tell you for sure that it really reduces capillary damage. I would assume if it greatly reduces macro damage…actual rupture of capillaries, it will also decrease leakage. It is the leakage that leads to the discoloration.
Warm up for 5-10 minutes with a hot-water bottle ~115 F. Apply the clamp gradually, don’t tighten it down all at once. Take it easy with the squeezes and other pressure enhancers…especially when you first start clamping. More pressure does not equal better or faster gains.
In my experience, hanging related discoloration is primarily a function of faulty wrapping and attachment. A HTW helps to create ideal, or near perfect wrapping and attachment. This in turn helps to prevent discoloration.
Clamping related discoloration is more a function using too much pressure or applying it too quickly. In other words, when hanging, if you get the wrapping and attachment right, you can hang very heavy weight and not get discoloration. Whereas with clamping too much pressure will cause discoloration with or without a HTW.

Again, great post. I wonder if counter pressure at the capillary level can reduce or eliminate discoloration. My theory is it MAY. Hence the experiment. I am asking those who are getting discoloration to try it and see if it slows or stops the progression.
