The FIN-ACK latency threshold was written as 100000 (100ms) instead
of the intended 1000000 (1 second). Connections completing between
100ms and 1 second were incorrectly flagged as high-latency outliers
and printed as failures on loaded systems.

Add the missing zero to restore the intended 1 second threshold.
