How to read this

The figure is the OUTBOUND leg. The walk back costs the same hours, which is why the daylight is halved rather than spent.
Use your round-trip average, not your fresh-legs pace. Breaks, photos, snacks and the last tired mile are all in that number.
Decide the turnaround before you start walking. Deciding it at the turnaround, with the summit in sight, is how people get benighted.
