You said it here....I put it in bold....
I can agree that beginners don't have the eye or knowledge to diagnose real
problems
What you said above is what I meant to post. But speed posting without proof reading took place because this isn't the highlight of my day and activities.
but I'd say the majority of experienced ameteur players do. Hell, I'd even go as far as saying that with the tons of instructional material available in books and on YouTube, even a beginner nowadays has access to the knowledge that'll allow them to self-analyze and diagnose their own pool stroke or golf swing or whatever.
Access is better than it's ever been in our history. But it still doesn't mean they can "get it" from that alone. Things really need to be taught and learned in sequential order which they don't know. It's piece mill patched together.
It just takes more effort than running to an instructor for immediate answers. But since most people just want answers, it makes better sense to get help from an instructor if you don't already have the knowledge needed to self-analyze.
When you first started playing pool or guitar and knew then what you know now, how much better would you have been in a far shorter period of time than you were through trial and error on your own?
That having been said, how does an experienced instructor in ANYTHING hurt, especially if they're REALLY good at teaching, diagnosing, and playing?
Are you saying you'd rather learn everything on your own or spend a week with Aranis to learn exactly how he does it all mechanically and how his thought processes take him around the table shot by shot?
Please don't make the wrong answer and look totally stupid...for your sake.
