I'd be the first to agree with you! How about "Reading Between the Lines of Lydiard"? Lorraine (Moller) and I have been working on that.
A lot of us who knew Arthur would agree and we are trying to clarify his ideas. Nobby spends tons of time doing so and I also am looking forward to what he comes up with.
i think that's the problem with Lydiard, unless you trained under him or spoke to him directly about his theories, his books are "difficult" to understand or not very clear. i hope his disciples can write something that will supplement his books.
