How is the average computed?

All entries convert to seconds, are summed and divided by the count, then formatted back — the arithmetic mean, the same as averaging numbers.

What's the midpoint for?

It's the halfway value between the fastest and slowest entries — a quick sense of range, distinct from the mean when outliers exist.
