This is awesome. He has my favorite video teaching style BY FAR. Shows the move, hits a few key points, shows it again in slo-mo from a few angles, done. I don't need a lot of conceptual discussion, just show me the move and tell me how not to fuck it up.
I think at a certain level the highlights are more beneficial, as only so much of it applies to you if you're already familiar with wrestling (e.g. general strategies, proper setups, advantageous tie ups, etc.).
I know very little about wrestling so the longer explanations can be helpful. I've been looking at Salamone's stuff and while it is really long and sometimes tedious, he clearly explains underlying concepts that many videos only imply. To be fair, I don't know that I can blame the "many videos" I'm referring to because it's rare that they are made as part of a larger, comprehensive system.
To speak to your point, I don't know that I could go back now and rewatch Hall's videos on the triangle but at the time (blue belt) it was amazing to be walked through all the entries and potential counters. Now I can usually just focus on one or two cues to tighten things up since most of the major holes are gone. I feel like I had to still initially go through that tedious process before I could boil it down to a couple cues, however.
To use an analogy, I could read and memorize all the summary notes at the end of the chapter but I still have to go through the process of reading the chapter and solving questions to internalize the info in my own way - there's no real way around the hard work (for me).
Kolat's thing couldn't have been released at a better time. It'll help me not get too lost in the details as I continue to go over Salamone's stuff.
To bring it back home, I think it just matters what level you are. I hate to always reference Holt but he had a cool article where he mentioned that the drilling to formal instruction ratio should increase as practitioners advance. I believe you said you mentioned most of your training consisted of off schedule sessions? Maybe this type of format would do a lot to attract practitioners like you to normal class, which I think is a huge problem (the lack of incentive to attend regular classes, that is). Advanced practitioners can be given brief cues or reminders to focus on while drilling. More in depth or discrete instruction can be given to those who want it or don't feel they have the prerequisite skill to immediately drill.
