Welcome. Be sure to share the vids of Dan and you playing and it's an early present for everyone! Oh and enjoy all the benefits of fast laning thanks to this board and what you pick up from Dan. I bet it's a ton of goodies. Your holiday presents arrived already
When putting try to stay chest squared to the basket all through the throw.
You were releasing many drives to the right. If it's not intentional then it's the same problem you're having with your forehand drives. Your arm is moving too fast to about 10" short of the release and in that final 10" you can't accelerate fast enough to force a clean rip off the fingers as easily. When your arm is at too fast of a speed too early.
With backhand drives another possible cure to releasing right apart from slow arm speed until the last 10" and then punching forward is to plant the final step with the right leg about 2-4" to the right of where you're now.
There's a fundamental reason why so many of your drives end up so high and stall. There's a rising vector in the flight of the disc when your arm is at hip height at the reach back and face height at the release. It'll feel odd to many to keep the arm at shoulder height all through the throw. There are people who are in between that height to hip level but they're able to keep the disc at a constant height from the ground during the throw. It's easiest to not raise the disc while it's at shoulder height. Higher than that and most players will likely loose power by forcing the arm into an unnatural position.
I didn't check if you were altering the amount of reach back for open long drives for maximum golf distance. For those your back should be turned to face the target at the farthest point of the reach back. Not breaking eye contact with the target for shorter or hazardous holes is a great idea but it'll cap your distance big time. Especially over time when you get other fundamentals right.
Reducing height is easier when you manage to maintain your wrist down as it opens. The natural tendency of the wrist is to raise and it's automatic due to the bones being shaped and positioned like they are. To keep the wrist down until the hand is at hand shaking position but bent down you need to use muscle power. That must not be started too early or it'll rob you of serious power and distance. The time to start to applying power to keeping your wrist down is about when the wrist starts to open.
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.
