In the diagrams, the numbered Places of the Dancers in the Full set, i.e., the Places in which they started the dance, are shown in Times New Roman font in the upper left part of the Dancer's symbol; their numbered Places in the Active set, i.e., the Places in which they started the current Repeat, are shown in Helvetica font in the lower right part.
On the first time through (the first Repeat), the 1st, 2nd and 3rd Couples dance while the 4th Couple stand in Places as shown in the following diagram.
At the end of the second Repeat, the 1st Couple would naturally reach 3rd Place of the Full set; instead, they Drop Down to 4th Place of the Full set, using whatever movement is natural and will not impede the 4th Couple (who will have to move Up quickly into 3rd Place of the Full set if they have to start immediately at the beginning of the third Repeat). The Couples are now in the order 2s3s4s1s; the dance continues with each Couple becoming the 1st Couple of the Active set and dancing twice through (two Repeats), in turn, Dropping to 4th Place of the Full set at the end of the second Repeat. The following diagram shows the Dancers at the beginning of the fourth Repeat.
While this is the most common format, it can confuse the Beginner who needs to be careful to remember which 3 Couples are dancing the current Repeat and which Couple is not. S/he should not be tempted to join in the dancing when s/he is supposed to be Standing still (in 4th Place of the Full set for the odd-numbered Repeats or 1st Place for the even), awaiting the next Repeat when s/he will be involved; more importantly, while dancing a Repeat, s/he should not attempt to include the Couple who are Standing awaiting their turn in the next Repeat.
Another way of viewing this Progression is the sequence in which each Dancer performs each Place of the 8 Repeats. For the Original 1st Couple this is:
11 43 32 20
where 4 means Standing in 4th Place and 0 means Standing at the Top, in each case while the other three Couples are dancing as the Active set. The Original 4th Couple follow the same sequence starting two Repeats down the list, i.e.,
43 32 20 11
and similarly for the other two Couples.
As an encore in dances of this format, usually only one Repeat per Couple is danced ("Once and to the Bottom"). On completing their Repeat, the 1st Couple of the Active set must Drop especially quickly to 4th Place, using a movement which will not impede the two Couples who need to move Up to start the new Repeat. Again, it has become common practice for 4th Couple not to Drop to 4th Place but instead to stay in 2nd Place at the end of the last Repeat of the encore.
At a Ball, and in order to avoid having keen Dancers sitting out, the MC may allow a fifth Couple in one or more Sets; after completing their two Repeats as 1st Couple of the Active set, the Original 1st, 2nd and 3rd Couples Drop to 5th Place. Unless the MC advises otherwise, the 4th and 5th Couples should dance as 1st Couple of the Active set once only, 4th Couple Dropping to 5th Place at the end of the 7th Repeat. This does mean that 2nd Couple of the Full set are penalized by being able to perform in only four Repeats whereas the others perform in five. In a dance where the Drop to 5th Place is particularly difficult (see Flow between repeats), at the end of the 7th Repeat the Dancing Couple can conveniently stay in 2nd Place of the Full set from which they dance as 2nd Couple of the final Repeat; however, as John Marshall of Cheltenham Scottish Society points out, this does mean that 2nd Couple of the Full set are penalized even more by being able to perform in only three of the eight Repeats.
Alternatively, the MC may invite three Couples to dance as a "3 Couple Set"; on completing their Repeat, the 1st Couple of the Active set must move especially quickly Down to 3rd Place and the 3rd Couple of the Active set must move quickly Up to 2nd Place ready to start the new Repeat. The actual movement by the 1st Couple should be chosen to fit with the movements on bar 1 of the next Repeat when the 2nd and 3rd Couples become the new 1st and 2nd Couples.
With this Progression, the order in which the Original Couples of the Full set find themselves at the start of each of the eight Repeats of the complete dance is as follows. Again, the Standing Couple is shown in italic; the Active set for each Repeat has the 1st Couple shown in bold face and the Supporting couples (the 2nd and 3rd Couples of the Active set) in roman face:
