Movement survives the slowdown
Walking, slowing and changing cadence remain legitimate forms of continued movement.
The field does not translate reduced speed into procedural failure.

SLOWING / OBSERVED
STOPPING / PERMITTED
RESTARTING / AVAILABLE
21.A / PACE
Walking, slowing and changing cadence remain legitimate forms of continued movement.
The field does not translate reduced speed into procedural failure.

A stop may be temporary, prolonged or final. None is assigned a moral value.
When movement returns, the prior pause remains part of the record.
