10 seconds sounds better to me. The only time that records will conflict will be during a restart of a workspace, which I would guess takes 20-30 seconds in the fastest possible template.

We aren't just worried about records with conflicting IP addresses, we are worried about turning off Coder Connect entirely and then using some other tool to connect to the workspace, and having the OS return a stale record indicating that Coder Connect is running when it isn't.
So, the relevant time scale is how quickly a human can turn off Coder Connect and then switch to another tool, not a workspace restart.
