I have recently been given a 3rd edition TGM book and I am finding it facinating the changes from the 3rd to the 6th and 7th editions. I might be wrong but the in the 3rd Homer seems to give more guidance to helping the pupil find their stroke pattern. Also in the 3rd there are 5 imperatives (lag pressure, flat left wrist, balance, rhythm and steady head). Can you throw any of your insight into the changes in the editions and your feeling for why Homer did them.
