Calculation method
Calculation method
Walking block start/end timestamps
Add each supplied walking duration in order; insert one break between adjacent blocks.
Between-block break start/end timestamps
List only between-block intervals; no final break is added.
Modeled arrival after final walk
Finish after the final walking block.
Total walking minutes
Sum walking blocks.
Total between-block break minutes
(block count−1)×supplied break duration.
Symbols and units
- a
- Whole walking-block minutes, comma-separated
- b
- Break minutes between blocks
- c
- Start timestamp, fixed offset
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- An explicit walking/break timetable, not a recommended rest interval or pace forecast. Supplied durations use a fixed-offset clock, and zero-duration blocks are retained literally.
