Lady's part of a Big Top:

1. LF forward & across in PP & CBMP
2. RF side, around partner's RF, in promenade position.
3. While pivoting on RF, brush LF to RF, without weight.
4. LF forward in CBMP (reverse pivot). Return to closed position between 3 & 4, similar to a slip pivot action.

If I had to approximate the amount of turn, I might break it down like so:

3/8 between 1 & 2
3/8 between 2 & 3
3/8 on 3 (pivot)
1/8 between 3 & 4
3/8 on 4 (pivot)

Resulting alignments would be:

Begin facing center in PP.
1. Moving towards DC facing center.
2. Backing DC
3. Facing LOD
4. Towards DC, end backing LOD.

Hope that makes sense.

Jonathan
