clarification
But it's important to understand when that turn starts, and the "almost useless" book tells you that you commence to turn on step 1. I know a lot is lost in words, but you almost make it sound like you just flip around at the end of the 2nd step, having done nothing to create that rotation up until that point. I know you don't do that, or it just wouldn't work, but it almost sounds that way in the description. If you don't believe me, please watch a video of yourself or any great VW dancer slowed down and you'll see that in normal situations, the turns starts sooner than you may think.
This sentence you wrote in the first post still baffles me:
I've got nothing but goodwill here, and I'm not trying to be argumentative, but taking two back steps with no foot turn and then rotating is just plain wrong, and impossible to dance cleanly and consistently. As we have no way to communicate this in person, if you can find me one example of a video where you can see it danced this way, I will be convinced that it at least is possible (not that you care if I'm convinced I'm sure ). Just one example. In fact, if anyone else reading this has ever danced it this way, I'd like to hear why.
Again, please understand my intent is only to clarify and understand, not to argue!
Hi Josh: Yeah, my description is a little confusing. I guess there are three things that apply to dance steps: 1) what something looks like, 2) what you were trying to achieve / thinking about, and 3) what actually happens.
The two main issues I see with VW that causes underturn are the person going forward turning too early, and then the person going backward turning too early. That's why I really think of taking two back steps. My left foot on 2 will be turned out quite a bit, and my hips are probably turned out slightly as well (I'll have to try this later), but if I tried to turn it, I would have overturned. This overturn when going backwards forces the person going forward to turn too early, and generally step outside and away from the partnership, causing underturn. So I'm thinking of going back, I actually turn slightly, and who knows what it actually looks like.
For VW, most people watch VW and see people turning continuously and try to imitate that. So let's see if I can't break it down and hopefully you can tell me if it makes sense.

Especially since if I can't explain it clearly, then I'm probably doing something that doesn't make sense.
Going forward:
a) I start with my body facing DW. It can be argued that my feet are also facing that direction. I like my body turned more to the right than my feet though, so my feet tends to be closer to LOD.
b) I torque my body slightly to lead my partner to step back and very slightly (one foot width) to the right. CBM is usually the word used here, but given the rather contentious thread about that, I'll leave that word out of our discussion.

I take a forward step down LOD, aiming down & compressing my left leg, left side leading, little to no body turn, no foot turn. End of beat 1.
c) I take another step forward with right foot. I'm still trying to keep my right foot going past my left foot. At the end of that swinging leg, I turn slightly so that my right side is leading, which causes my foot to turn slightly as well. My body therefore turns approximately 1/4. The amount of turn of my foot is unimportant, as long as I keep my frame with my partner. I.e., I turn because my partner hasn't moved as far. End of beat 2.
d) The linear momentum allows me to continue my weight onto my right foot, the rotational momentum draws my left foot in front of my right. My body turns left another 1/8 to 1/4, ending backing LOD to DW. As soon as my left foot comes underneath my body I release my right leg. End of beat 3.
Going backward:
e) I take a step back and very slightly right with my right foot, aiming down. This is not a rotational step per se (I'll let the person going forward generate any torque). My right foot ends up in front of my partner's left foot. My left side is still leading. End of beat 4.
f) I continue taking a step in the same direction with my left foot. There is no change in weight (left foot points). I use my momentum from the previous step to help my partner take a second large forward step, slightly past me. My body will turn slightly as my partner goes past, causing me to turn approximately 1/4. My foot will probably be even more open (turn 3/8?) but it
starts as a back step, not a side step. Where my foot goes doesn't concern me -- all that is important is me moving linearly, my partner moving linearly, and my partner going slightly past me. To stay in the frame and to help my partner I have to rotate as well. End of beat 5.
g) My right foot closes to my left foot, completing any turns to stay with my partner. As soon as my right foot closes, I release my left foot to move. My body will turn approximately 1/8. End of beat 6.
Does that make sense? Can you point out where your thinking disagrees with mine? Thanks!
