EirDance — illustrated overview Silent video with English text. It combines explanatory copy with a labelled reference screenshot or educational illustration; it is not a new recording of the workflow. Show the quick changes before show night. A running order needs room for the dancers who appear more than once. EirDance reviews a recital roster against your change-gap rules and helps you adjust the sequence before exporting run-order and change sheets. Reference screenshot: Real EirDance result for a synthetic 42-routine, 90-dancer roster: optimization reduced 157 hard conflicts to zero; 10 quick changes remain for backstage review. The run-order CSV was exported. In the fictional nine-routine example, the optimizer reduces eight hard conflicts to zero while keeping the opening and finale fixed. That is a sample result, not a guarantee: review remaining quick-change flags, every conflict and the exported packet before a live show. Walk through the recital. https://perunlight.com/guides/eir-dance/ Full compatibility and limits: https://perunlight.com/guides/eir-dance/
