Output and limitations

A presentation includes pauses for demonstrations, audience reactions and transitions. Add those pauses separately from spoken words to estimate a rehearsal schedule. Delivery speed can be reduced for technical material or a multilingual audience; the entered pace remains a planning assumption.
