Kidding, he sounds like he’s doing his best. But IMHO, the reason why people who are taught by a friend or family member are more likely to be in an accident than those who teach themselves is because the well-meaning friend is always so helpful and ready with the next lesson.
You might be best served by spending an hour(s?) practicing finding the friction point on the clutch. Find the point, glide up to 5-8 mph, pull in the clutch and ease to a stop. Then do it again, and again until you reach the end of the lot. Now duckwalk a nice wide turn and start over. Keep doing it until it feels comfortable (and this may be spread over a few days). Then you can start adding things like feeling how the rear brake feels, doing some slow S-turn, etc…
Have fun learning and don’t be in a rush.
Lastly, you sound a bit like me with all the reading and research (my wife gives me crap all the time — “just buy it already” is a frequent comment). The study is cool if you enjoy it , but don’t let it lead to “analysis paralysis.” There’s a time for reading about traffic accident stats, bike ergonomics, etc…, and then there a time to just relax and feel how you feel on the bike and how it responds to your control.
