Thanks for the guidance @WildRose. I have continued practicing this skill with dry-fire.
I have not been to the range much the last couple of months, but spent a whole range session practicing this two weeks ago. In some ways the live fire went better than expected, but target acquisition was markedly slower and overall accuracy reduced but I will continue working on it. I set 2 targets up side by side. I am right eye dominant, and of significance to me was how much better I did with the right side target vs. the left side target. My guess is the left side target was obstructed by hands and firearm when shooting the right side one, and my brain was confused with a clear view of both targets when shooting the left hand target.
