Sorry, Ray. You're talking twaddle.
Yes, I must say, I was a better shot ears ago. That's easy for me to say. And they're just words and taken on trust. But I can't substantiate that claim. However, I KNOW I was a better shot back then as I had the opportunity to shoot and practice more often. Sometimes, these days, weeks can go by between sessions. And I mostly shoot seated now whereas, years ago, I practised from different positions. I am, however, as you know, a fan of The Boinger and low mag scopes.
I agree with Phil about the specifications of modern courses - distances, range traps, kill zone size etc.
