Not terrible at all for an accuracy throw but there is room for improvement. If you turn your back, back of the head and heels at the target in the x step you can reach much farther back and when you can throw without losing confidence, balance, timing and the ability to use the conscious mind to control the muscles to get a fast movement you should quickly see 10-20' increase in distance with more available later with practice. Your left knee stays bent indicating that you don't push with the left leg at all. That robs a lot of power. Pushing forward with the left leg will push you body forward dropping the front of the disc lower. Different arm pull heights can change the ability to keep the front of the disc down. People are built differently so it is hard to say if a lower or a higher arm pull height would give you more power. Good indicators for best pull height are distance, looseness of the muscles and the quickness of the snap. Improve in one and you've probably improved in all of them. So you should test different pull heights and distance is the easiest to measure.
You almost stopped in mid throw and that is taking the pause too far. The arm should move forward in the pause and there should be some slow residual movement forward of the torso from the plant step. You did not get the elbow in front of the rest of the body so that killed the snap alone. Never mind not twisting the hips or turning the shoulders as much as they could be utilized. The disc should get to the right pec area before the elbow starts to straighten.
Disc nose angle and apex height consistency training should be done with flat throws with non flipping discs. Drivers punish the most for nose up angle so they might be a good idea for that. Putters punish the most with low apex heights becoming too short with low apexes. Pushing the weight forward (you were ok here) with the left leg helps in creating consistency in eliminating staying weight back problems. Making a mock slow throw before the actual one allows you to feel and look at the straight line that the disc takes. You should watch the height of the reach back especially but also see that the height does not change in the mock pull. Then the real throw should mimick the mock pull feeling of the arm. Your wrist was not bent down at the ripping out of the disc from the hand moment which raises the front of the disc. A major problem. Some shots looked like the disc slipped out of your hand=less power and missing to the left which is more evident in a flat and anny throw than in a hyzer.
You were super relaxed in the arm. You did not really accelerate the arm by using the arm muscles much at all. It is not just a matter of getting proper timings and body positions like getting the elbow forward you also need to put a lot of oomph into the movements when you are going for distance. One thing that helps in getting the elbow forward before straightening the elbow is to stop the right leg in place for a while after the plant step hits the ground and the ball of the right foot is airborne. That bracing should last until you puch back with the right leg simultaneously with the left leg pushing forward. Then the right leg can relax some. Not too much to fall down
Even more power is available from the legs by sacrificing accuracy and consistency theoretical top limits by doing a curving x step in a double pivot. Where the x step left leg pivots on the ball of the foot running from back right to the center of the tee and the plant step lands in the right front corner and pivots on the heel. Hyzer is controlled by arm swing plane and the leg work is way different to an accuracy throw detailed in my signature.
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.
