There is nothing here that is different from standard technique. I'm looking for the view of a "seasoned" dancer that shows how the technique is inadequate to describe the movements required at a high level.

As for your comment that lady moves later than the man, or she arrives first, that supposes that they move at a constant speed, but they don't. Both step on beats one and two, but the man has a faster foot speed and flight, as he has further to travel. If she doesn't move at the same time as he moves, she cannot achieve the body rotation that would allow him to pass.

Anonymouse. Some how we have gone away from the argument which was NFR on the first step of the Natural Turn in the International Style Waltz for the lady.
So lets go along with your side track which you instigated
You know as well as i do that there is no Quick Open Reverse in the Waltz and the Foxtrot according to the technique book by Alex Moore. There is in the Quickstep and it ends on step four which becomes the first step of the Progressive Chasse. So we go to the Progressive Chasse Page 47. The first step for the man has No Foot Rise. For the lady there is Foot Rise.
Tell me this. Is there Foot Rise for the lady on the very first step of a Quarter turn in the Quickstep. Also is there rise on the first step of the Quarter Turn for the man.
Should a Professional who is teaching know this. Of course they should. They should also explain that if the lady were to Foot Rise on that step , which is the very first step we ever learn in the Quickstep.She will alter her body position with the man by taking his centre away from him. Usually with a beginner instead of the confusing NFR it is often said that the person on the inside, takes a smaller step than the person who has the longest distance to travel, they being on the outside of the Quarter Turn. End of story. I think that covers the NFR part so should we leave it right there.
The answer to the original qiuestion some 75 answers ago. Of course a Professional should know the sylabus.

"You know as well as i do that there is no Quick Open Reverse in the Waltz and the Foxtrot according to the technique book by Alex Moore. There is in the Quickstep and it ends on step four which becomes the first step of the Progressive Chasse. So we go to the Progressive Chasse Page 47."

No, we stay with the quick open reverse, because it is that, and not the progressive chasse, which is the reversed roles analog of the feather finish in so many respects. (The progressive chasse is not comparable to either, because it has the type of rise needed to close the feet, in contrast to the type of rise used in the quick open reverse and the feather finish which will pass the feet)

You seem to prefer to change the subject rather than confront the problem in your line of reasoning.

You will not be able to explain difference in proper footwork between these two situations until you take the difference between the man's role in dancing and the lady's role in dancing into account.

Anonymous. In which book is there a Quick Open Reverse in the Foxtrot described.
This whole things goes back to the question asked by John Power which was Should a Professional Know The Syllabus.
Unfortunately you are obviously one of those who was not taught correctly simply because you have no idea what No Foot Rise is about otherwise you wouldn't be arguing here. Let me tell you once and for all. When you see the letters NFR on the ladies LF it means that that next step, a T. comes from a flat foot on the supporting leg which is of course is the ladies fore mentioned LF.
Is that too hard to understand.

Quick Open Reverse is charted (in full) as a standard Foxtrot figure in Howard (2007) at page 99 and is a standard syllabus figure.

"Unfortunately you are obviously one of those who was not taught correctly simply because you have no idea what No Foot Rise is about"

There is no doubt about what no foot rise is about, but that is not the subject.

The subject was why the man has THT and foot rise on the inside of the feather finish, in contrast the TH and NFR that the lady has when she does the comparable action on the inside of the quick open reverse.

And the reason of course is that even when put in a comparable situation, the man will act differently than the lady would, because his role in the couple is different - he must remain in a dominant position, and cannot be under the swing of step 3 in the way that the lady would be if she where the one who had been on the inside of the turn..

(Note that this difference only applies to the open turns, not to actions that close the feet on step 3)

Anonymous. I'm still trying to make sense out of this one. Are we discusing the 4th to 5th step of a Reverse Turn in the Foxtrot International Style. If we are. When we step to the side it will always be from a Toe to a Toe so we have THT on the RF for the man on that 4th step. 5th step is a T. The ladies 4th step is HT followed by a TH on her 5th step.
Step 6 for the lady is TH NFR. The man on 6 has a TH.
From this you will notice that side steps come from a Toe to a Toe for both. In writting it looks rather complicated. But to anybody who has passed a Bronze medal it is quite simple.
What I am pointing out her is we never step to the side from a flat foot to a Toe. This also includes the first to the second step of the Reverse Turn for the man.

A side step departs from the toe of the standing foot regardless if the standing foot was placed THT or TH, NFR.

The reason the THT is used in the feather finish is because if the mans dominant position over the lady requires him to return to the toe before the end of the step. If the lady dances the comparable situation in an open reverse she has TH, NFR which is to say that she only returns to the toe of that foot after the defined end of its step, so the toe is not mentioned again despite its being eventually used.

Anonymous. So we are describing the 6th step of a Feather Finish on an Open Reverse Turn. That is where the ladies feet pass instead of a Heel Turn. A Feather Finish is the same even if there was a Heel Turn.
What I disagree with is saying the man's dominant position on that sixth step.
The lady has the furthest to go and has to be allowed to pass. An over agressive step there will make the ladies steps impossible and she will finish back weighted. He should stay on the 5th step longer untill the lady has past and allow her to finish her step. Speak up ladies. How many of you get hauled onto that particular step. Or are you accepting that is the way it is supposed to be. If it is not completely comfortable it is wrong.

No Cyd, we are contrasting the mans action on the first step of a feather finish to the ladys action in the comparable situation of the first step of an open reverse. He uses THT because he is in a more dominant position, but when she does it she uses TH NFR.

In both cases the departure is from the toe of the right foot because the left foot is moving to the side. However he returns to his right toe before the end of step having actual foot rise to be in a dominant position over her, wheras if she does it she remains lower and returns to the toe of her right foot only after her left has passed it to formally end the step, so her return to the toe is not mentioned.
