Good for you Richard and glad to see others with similar needs that had to switch and work through it chime in. What a great feeling when something old becomes something new again and that light bulb clicks. I'll bet you were as giddy as a school girl when you hit 10 in a row but then 30/35, wow! What a great moment to get that endorphin shot and build that confidence up. I'll bet you were soaring a mile high off the ground without need of your flying contraption. Thanks for sharing.
BTW there is so much shotgun shooting content out there you are probably rediscovering about eye control and letting body mechanics and instincts take over. I can only imagine how awkward that is at first akin to probably like learning to swing a football bat. Glad you were able get some success to build off of. Sounds like you have found the right base process and technique for a good foundation to grow from. Remember if your not green your not growing so read up more on those techniques like the three shell trick and breaking down the process. Good stuff.
