The surface is shared space
We talk about the pool as a workbench everyone touches: how you turn, how you rest at the T, and how you leave space for the next person is part of a courtesy layer that is separate from your training plan. That is why the Swim and Recovery areas live on their own pages with different section shapes—one for rhythm, one for dry time.
When a facility posts a new depth marker or a temporary closing, staff on the ground always win over any paragraph here. Treat this as orientation before you listen to them in real time.
