your head moves to the left as you start your backswing try keeping it a bit more sturdy,keep your chin up so you can put your left shoulder there to keep your swing on plane.try that and see what happens.
to me its mostly ball striking,hitting fairways and greens the more grens you hit the more birdie ops you have i say practice with an instructor the full swing
worked on tempo backswing length position at the top (still not where i want it want it slightly flatter) so what do yall think?sorry for the bad angles
