Only time early days I was on the indoor monitor was right at the start of my lessons with him when my pro wanted to show me my existing swing path and where on the club face I was hitting the ball - we’d already been on the range so he’s seen the issue - and then he showed me the swing path he wanted me to work towards. He does not video my golf swing - ever. He considers that it would be a problematic distraction for me.Sorry I misread you on the flexibility. I like to see the number. The numbers are fine as long as the coach is just using them to explain what they are teaching you but any good coach can tell you from your ball flight what is happening so I’m just saying find the right coach irrespective.
He told me what I needed to do in my address position (he photographed me in my existing address position and in the position he wanted me to adopt) for starters and gave me one shot (not swing) thought, and I immediately saw the difference - both in swing path and clubface strike, so I knew what I had to do - and so it has been simply working on my address position and keeping that one shot thought in my mid - hit a fade - every shot.
Then some months later we went back on the monitor to see how I was doing. He wasn’t interested so much in the shots I was hitting, he wanted me to see my swing path and club face strike, and if and how much it had changed. I still no nothing of the actual numbers - I just know that if I keep on building consistency in my address and keep my one shot thought in my I will get there.
