Great video, thanks! I'm not sure it exactly addresses these points, but a lot of good ideas are in there.

To me, "professionally-accepted" means there are a lot of experts who can be identified, they routinely discuss and formalize agreements on key points in professional practice, and their views and conclusions can be discovered by normal users (meaning cyclists) with reasonable effort. AND they actually do agree on the point in question. I can accept that one expert can agree with you. I've been on this subforum since it started and it has been mainly about cyclists saying "my butt/hands/back/glutes hurt, what do I do?" Of course fitting is often a recommendation, but we just as often have, "got a fit, >$150 fee, now I'm worse off, what do I do?"

If "professional fitter" means someone who will take my money, then I do not want to ever meet a professional fitter. I had an excellent one, and several that were not positive and productive, and did not improve my comfort and performance. The best fit I have ever had was developed by me while training for a tour. I don't see the need to see one at this point, for myself. If it could ever mean someone was registered, licensed, and carried societal endorsements of successful work, I would have a lot more respect.

The best I can do is try to understand the actual complaint the poster of a message has, and share how in my experience I have resolved (or not!) similar matters. I think I made that clear in my post, which you responded to. And I never advocated cranking up the saddle drastically. I suggested raising it a millimeter at a time to reduce what for me is a source of joint stress. I intended for him not to go past or even to the point of hip-rocking or any such destructive condition. It takes some patience and methodical approach to do this, but it's not impossible. I assume the OP has enough sense to ignore my input if s/he does not have the same complaint or a similar one.
