You should decide which way you wanna throw. For accuracy maxed out or reduced accuracy with more power generation. At the moment you throw with a form that is the second most power generating topped only by 360. The trouble with your form is that in order to get the added weight shift you need to push harder with the left leg and that is problematic in poor grip conditions and when you are tired. You must be able to push hard each time in order to not lose consistency and accuracy. The body parts aren't moving in the same direction all the time so the body gets contorted and that creates more stress thus fatigue and injury risk. Additionally when any part of the body tires out before the others the timing and accuracy changes. A straight line toss has the disc moving in a straight line for longer. http://www.youtube.com/watch?v=9pk23LeyVk4
You ran out of the tee so the follow through was compromised. So any conclusions are iffy. What is clear is that you raised the rear leg off of the ground before you had the disc rip out. That makes it difficult to turn toward the target and not miss left. You have to compensate with the arm and that makes timing a bitch if you even notice the problem and have the time to react and compensate and you can say good bye to consistency.
Were you trying to do a control or max D shot? You may wanna try running in a straight line and aligning each body motion to go straight at the target and pulling the disc in a straight line. At the moment your running direction and plant position is for an anny and the arm moved in a hyzer.
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
