The Light,
I agree with your post on several levels.
I have an older copy of the Coe/Martin Book, which I have read and still reference. I have a Lydiard book too, which I know well and know where to find his other stuff should I need to.
The first thought that entered my mind upon first reading Coe/Martin, was the similarities to Lydiard. Someone at that time, was indicating the differences between the two methods, which DO exist, as he had said they do.
However, I was surprised by the similarities - expecting as outlined mainly differences.
One thing, which really speaks to me from Daniels, Kellog, Lydiard and others I guess - especially Lydiard, is the whole 'understanding what you are doing' thing in his coaching. Empowering the athlete.
Also, the simplistic-ness as in lighter shoes, simply run slower if you are tired... etc etc.
I like the wholism-thing too.
The body and mind are their own experiment, each one of us. The Christian Calendar, the watch, the exactness of time and distance are opposite to the body, which is maleable, subject to it's own ability to recover; different on different days depending on how you eat, weather, age, natural ability, physical and mental stresses etc etc.
How can it be optimum to say to one person or all people, "today we do 15 x 400, no less, no more and exactly in 63 seconds per, with exactly X recovery".
It (TO ME) just makes more sense to set about doing 15 x 400 in 63 with caveats. - Do the 15 if recovered and prepared, if at anytime it doesn't seem right, correct what you are doing, like less/more volume, less/more recovery, less/more speed etc. Knowing the point is (in speed work) to bring down the ph level temporarily.
I see the 'specific' vs. 'know thyself' approaches as the only MAJOR deal maker difference between the two methods of Coe/Martin vs Lydiard.
I don't think a person can go wrong folling either method, as they are similar in the route method.
