# CSV recordings notes
- There's always little trash at start and end of each file
- Each step is 60cm (`2B`) or 30cm (`1B`).
- Same path always. 1B have 18 steps, 2B have 9.
- Starting foot is RIGHT. Filenames with `L` suffix (*eg. 30L.csv*) means starting with LEFT foot.
# Recorded gait sequence
1. *(trash ~0.5s)* turn from laptop to start position
2. 9/18 steps
3. full stop
4. 180 turn
5. full stop
6. 9/18 steps
7. full stop.
8. *(trash ~0.5s)* turn toward laptop to stop check recording
