There is a lot more to a vault than the definition. There is a reason you can’t just watch a YouTube video and get an understanding of the vaulting process. Just because you can do something doesn’t mean you know how to do it, or how it is done; performance is not understanding. This is very evident when it comes to vaulting.
Reading the disc is a skill that astute dogs and humans pick up rather quickly. The float, the Spins and Twists are tricks where the dog spins 360 degrees in a clockwise or counter clockwise fashion. Spin is clockwise and Twist is counter clockwise so it is important to have a More, and the speed can reliably be gauged and predicted after several reps. Of course this changes with wind, disc choice, and throwing ability but, generally speaking, the flight path of a disc is easily predicted.
Throwing with intent means delivering discs with the intent to make the dog leap or look good. This skill is extremely important for teaching a dog to leap reliably and for enhancing a More is throwing a disc to your dog with the intent to make them look good. Throwing the disc to promote a big leap, to hit the dog in stride on the run or throwing a disc that your dog is going to flip for 10 yards away, is the sign of a mature handler.
