A little pressure and everything gets quick or waaaay to slow.
One of the things I see on the Tours is rehearsal of the setup cadence. It is a measured rhythm of everything before the shot is made.
Several of the mental coaches use the Golf Metronome to help establish and reinforce a consistent cadence. The heartbeat responds to the sound of the beep, walking pace adjusts, thinking is more clear, setup has a cadence, and the swing has a chance.
Consider putting this concept into your playing 🙂 Sam
