I’ve been working on stroke, trying to scratch in the same pocket as OB, CB set up three diamonds from OB, OB two diamonds from corner pocket, straight in shot. I can scratch now maybe every five-seven shots, and where I don’t scratch, I’m much closer than when I started. Checking that cue goes over the extra target donut to verify I’m cueing straight.
Every so often my elbow comes out a little, though less than before I started this drill.
Also, via video, and I can’t believe I was doing this, I found I was jumping up as I finished my stroke! I had no idea I was doing that. Still working on it all……
Sounds like you're on the right track. Keep it up!

 
 
		 
 
		 BTW, I opened my stance like a snooker stance, can see the shot line SO much better, can get my face and eyes much more square to the shot. Doesn’t seem to have hurt my ability to cue straight through the shot line.
