I had the book. It cost exactly $1.00 at a discount store and is pure fluff with absolutely nothing of value in terms training info. I donated it to a local library.
In terms of the supposed East German in training I think that it is due to a couple of things. From the mid-1970’s Americans became obsessed with GDR system. Lots of coaches were claiming to have knowledge of what was going on there, when in fact is very, very few westerners did. Connolly may not have even known that she wasn’t mimicking said system. My guess is that Vince Reel was at the heart of this “misunderstanding.”
