Good luck my friend. As Eisenberg said, it has all been done before. You can spin, flip, hop, jump anyway you like, but someone else has already done it. In a way it's like skateboarding. All the tricks have already been done, anything new that comes up is just a variation on a pre-existing trick or a combination. I don't mean to call the movements of parkour tricks, I'm just making a comparison. What's important is not that you create something entirely new, but rather that you do something that is new to you. It's about your individual progression and style, not what everyone else is doing. Make it your own and don't worry about what has or hasn't been done yet. BTW we were doing 180 and 360 precisions 30 years ago before we knew anything about anything. It was just fun, we weren't trying to create something new or practicing "precisions." It was jump and spin and land on this spot. The point is don't be trapped by a parkour "moves-list," it's about efficiency and flow. As Adam said, and I am paraphrasing, but let the environment dictate your movements, don't try to force your movements on your environment. If you are flowing things just kind of happen, and sometimes you create something new just because a particular obstacle requires a flexible approach and a set list of moves won't work.
P.S. If you pull off a 1440 precision, I want video. (That's a lot of spinning, 1080 would be hard enough.)
