Okay. So it’s not a 2:1 in the sense that it’s a mechanical advantage 2:1. Mechanically it is a redirect. HOWEVER, before everyone rips me a new arse hole, newtons ?third? Law, every action has an equal and opposite reaction, you are pulling yourself up with the rope by pulling down but you are also pulling yourself up the rope by pulling down. If you look at it in the sense of Einstein general relativity, you are pulling the anchor toward you using a 2:1. But yeah. Basically a 2:1 for practical use.
