Recorded per segment and used in both directions; see build-run-times.mjs for why, and for what is checked before that is allowed. The published times are whole minutes, so one hop is good to about a minute — but the rounding does not compound along a journey, because a sum of consecutive differences is just the last departure minus the first.",
