When there is any risk of ambiguity over who is Setting to whom, qualifying directions such as Up and down or on the Sides, should be included. On rare occasions, for example on the first bar of Petronella turn, the dancers Face away from each other though, in this example, they Turn on the spot in the next bar so as to Face each other at the end of the step.
When using Pas-de-basque or the Strathspey setting step, the Figure takes 2 bars; with other steps, the appropriate Timing applies, notably 4 bars for the Highland schottische setting step. The Strathspey setting step involves substantial movement to the right. When another dancer is Standing to the right of the dancer who is Setting (as, for example, in 1st Place on the Ladies' Side of a Longwise set with the dancer Setting in 2nd Place), there is a risk of collision, especially in a crowded ballroom; the line of the Setting step should be modified slightly so that the Setting dancer passes just in front of the Standing dancer on bar 1 and returns to the Starting Position on bar 2. This problem could also arise with the Highland schottische setting step but never with Pas-de-basque, of course, because there should be no sideways movement in the basic form of this Figure.
