I expected the heads to face each other in the center. A few graduated dancers asked me why, because they learned to face the center of each half of the set. That's how I learned it, too. But according to the definition I think the partner rule has a higher priority then the each side rule.
Am I right or wrong?
The reference point is determined by dividing the set in halves until all dancers in each section have the same center point. Dancers then work relative to that center point. That means, that from a 2x4 formation, dancers work in each 2x2.
