You can nitpick but I wasn't far off…
You say that the deadlift can be learned in a few sessions. Looking at the form of people in your hall of fame I believe it.
Nit pick, lol. Efficiency in the number of muscle groups covered is the same as it's easier to learn. Or at least it isn't very far off. Very good Richard.
Obviously you haven't seen many competitive deadlifters.
Have fun with yourself Richard.
