If the class takes N minutes and one person arrives 1 minute late, and the rest of the class is waiting for them, it does stack. Every one of those students lost a minute. Far worse than one student losing one minute.
Do "we" lose 2mins because we both spent 1 min commenting? That sounds like The Mythical of Man Month thinking... for me time is parallel and does not combine.
