"Anonymous. The Weave is a Reverse Weave which turns to the left anti clock after the Whisk."
The techniques books, and most dancers, call that the "weave from promenade".
"The 1/8 of a turn to get the feet to a position where the Weave can be performed correctly is on the Whisk. Not on the first step of the Weave which has no turn and is in CBMP."
And that is where you are wrong. For the SEVENTH time, the book says (in the weave from promenade, not the whisk):
"1/8 between preceding step and 1"
It it critically important to realize that this is a turn of the RIGHT foot only. The left foot does not turn.
And as for CBMP placement, I'd like to see anyone manage to place the step after a weave anywhere other than across in CBMP. It would be quite difficult to put it anywhere else as your partner is blocking most of your other choices.
The existence of turn does not alter the location where the right foot is placed, only it's orientation, which is now squarely to center in contrast to the DC alignment of the left foot.
But even if the turn did alter the foot placement, turn to the left would tend to putting it even more across in CBMP, not less.
"In fact tell me of any basic step where there is turn during step one.."
The weave from promenade taken after a whisk, as I have literally quoted it to you SEVEN times now.
So... the question still stands: how long are you going to continue denying that the ink in the book says what it in fact does??
