Re-measured all four recorded cases and added a fifth for the re-plan path, which needs 100 kS/s: at 10 kS/s the ring already covers 838 s, so no window the control can reach moves time_stride and the window probe re-plans nothing. Also notes that `stale` is 0 by construction while resequencing is on, and that the reservation cap is counted in packets, so its sample cost scales with the batch.
