Checkpoint Arrival Planner
Calculate running elapsed time and race-clock minutes for 1–20 checkpoints with an optional user cutoff. Constant average pace from your start at the entered race-clock offset. Stops are excluded. Cutoff must use the same race-clock minute origin; positive gap means before cutoff, negative means after. Calendar dates, route changes and time zones are not inferred.
