Yea, that’s a good question. As for myself I want to see what charlies programs look like in detail over a year so I can study it.
I understand the esoteric concepts as far as not getting away from strength training/speed work but how to exactly induce specific demands on the body over period of time is what I’m fighting with my own mind to understand.
Just so happens I got a copy of Gerald Mach’s book that is helping to shed some light as there are programs that are laid out in the final chapters.
