-The conditional throughput in this case is the median forwarding rate

-at the relevant lower bound intended load.
+The conditional throughput in this case is in principle the median forwarding rate
+among all trials at the relevant lower bound intended load.
+In practice, the search stops when missing trial results cannot
+disprove the load as a lower bound, so conditional throughput
+is the worst forwarding rate among the measured good trials.
