"Page 17. " Even the novice should remember that every step taken outside partner must be placed in CBMP to ensure that the two bodies are kept in close contact ". The Weave from a Promenade Position has CBMP on step one and step four. Page 158."
As I said repeatedly the subject step, which is the first of a chasse and not any part of a weave, is across in promenade and CBMP.
But the point is not the repeatedly stated fact that it is in CBMP, the point is that there is also an explicit instruction in the book to UTILIZE CBM.
Had the step been the first of a weave, we would step into CBMP as in any promenade but the man would not utilize CBM, because the couple is turning sharply enough towards the man that the CBM both partners usually have on the first step of promenades is not appropriate for him.
Please stop confusing the concepts of CBM and CBMP: the book is full of cases where you have one, or the other, or both together. They are distinct but compatible.
