Wonderful for prompt response and great explanation.
According to book, I understood full turn in outside spin ( lady 1/2 ,on right foot , 3/8 then 1/8 on her left foot responding to man's body. I like your explained the CBMP result here ; I asked local coach last night about the man's left foot side then " end with" LF back. I showed him tiny toe in pivot on LF , right turn 3/8, then driving force from HT of right foot ( still small step ( Man is inside as an axis from 0-1-2 ), he turns himself and lady to right remained 3/8 and 1/8 on his left foot . I blocked my brain here: how can do " end with " back step on same standing foot ? Or weight not fully be transfered ? You gave me very good answer, now I understood the appearance of "end with "left foot back " is due to standing left foot on its side position continuously turn further ( 1/4 here ). Cheers!
Yes, He said " end with" not and with . not 2 actions from LF, but gave hint of an appearance .
