I do understand your question but I find it hard to descibe how to do it. I had to try several times in diffrent ways before i managed to do it.I think it's hard. You have to twist and turn and climb up and down the ropes.I remember that the fourth jump I had to do in a position where I really didn't think it would work and then it did work! So try to jump in different positions even though it looks like it would fail.
My English and spelling isn't very good either but I hope you understand what I'm trying to say.
