I was very tired last night when I posted, so here are the disclaimers:
I probably should have said too few want to take the time to do it. I also would add I am guilty of it to. I never arrived to that point of view until I started giving training in AW.
Rgr moot, that list can only be explained to a point, but they have to gain experience to recognize it.
Let me give an example of what I mean by pointing out "What you should have done...":
First I would have a new guy read something like this
Basic ACM (token link for jackal)
Then I would keep refering back to those points in the DA.
"you did good on those first 2 merges, but then what happened? Were you watching what I was doing? You always need to look back after the merge so you know what the other guy is doing. I went up and you did a flat turn."
Then keep building on that, and throwing in new manovers.
"That was a chandell. Did you notice how I entered the merge that time? That is a tell-tale sign that its comming, but you might see it with a normal merge too. You have to adjust against it in the middle of your immel or you will lose position"
Then start throwing in change ups.
"that was a chop throttle immel. its hard to spot in progress if you're blacking out your first turn. if you are going to try it, you have to make that shot count, because you give E away doing it"
Being the salamander I am, I like to follow that with a lazy immel while they are test driving the chop throttle.

Over sessions, it naturally advances into more advanced stuff.
Stuff like that is worth months of flying time IMO.
