4:1 MA double sheeve pulleys
I was rigging a 4:1 MA double sheave pulley system when the training officer walked by and said use the double loop. I told him that I was not familiar with that so he coiled the rope in two loops and said, now you can't make a mistake and he walked off. Well as he left I felt dumb cause I did not see it and rigged it the way I knew would work, but I really wanted to understand his method but was afraid of looking dumb so I did not ask.
Can anyone explain this method if you know what I am talking about?
BTW we were rigging a system like in image.
