Depending on the synchronization between the burst pattern and the sampling

half the line rate, or the line rate, and all answers are equally valid in

They don't take a one-second sample every five minutes, they take the
five-minute average rate measured by their router.

Unless they're insane, or their routers don't support that.  I dunno who
makes routers that don't support that, though.
