Your official place uses the head-start handicap: every Group Y runner left 2 minutes after scratch, so the official clock measures finish order. Your actual time is the raw stopwatch from when you crossed the start to when you crossed the finish — that's what we use below to ask "how did you do versus runners who started with you, and how would you have stacked up in the other wave?"
