I see dead balls

This is a formula for success. Works wonders for golf. No reason it wouldn’t be just as effective for pool.The very first step is video. Find a way to mount your phone if nothing else. Shoot the same pretty tough shot ten times with the camera in front of you looking down the barrel so to speak. Then shoot the shot ten more times with the camera on the side and a final ten times with the camera directly behind you, 180 degrees from your first camera set up.
Chances are you can see some things that need correcting, sort them out. Another round of video to be sure the flaws are really gone and back the camera up and run racks. Consider your patterns, could they be better?
If you can't see flaws there are people that will analyze your video for a reasonable price. I would probably choose David Sapolis, BlackJack on here, if he is still doing this. Several more were, shouldn't be too hard or too expensive but your issues will probably jump out in video. What we think we are doing and what we are really doing are often two different things. Video at these angles doesn't lie!
Once again...you hit the nail on the head.Virtually no veteran player with a solid, but amateur level stroke, wants an extreme makeover, so I'd seriously consider leaving their fundamentals alone. The easiest ways for them to advance further as a player would be to improve their skills, and the areas most easily addressed are speed control, billiard theory, and pattern play. Addressing these skills will demonstrably improve their position play and their tactical play. Show them how to practice these skills to further develop them and they'll advance as a player without overhauling their fundamentals. It's a short cut to improvement.
On the other hand , if they ask for an extreme makeover, that's another matter. In that case, analyze and redevelop their fundamentals.

The "only" person I play that I "let win" on occasion is the wife. And that's selfish of me. She sucks but she's a game, at home. The only way my playing improves is by playing the fun shots, two rails, complicated kick-shots as she struggles on the bunnies. We typically play first to 3 in 8-ball and depending on how close to dinner it is, either goes 1-1 or 2-0 and I have to shine for a 3 rack run to win out. 30% of the time she wins her 3rd game because I tried a 15 rail bank shot on the 8 and scratch. Sometimes she'll surprise me with her own run and make the 8 after I've been sending it around the world through her 7 ball adventure.After the COVID shutdown, I realized socializing through pool was a primary source of enjoyment. Sometimes letting someone else wins can feel as good as not letting them get to the table.
