 === Faulty Hardware Link Detection ===

 A bad cable (faulty hardware link) is detected when all of the following  
conditions are met:
- * 100 divided by the total test time in seconds and multiplied by the  
proportion of the number of multiplicative downward congestion window  
adjustments to the total number of segments *is greater than 15*
+ * The [NDTTestMethodology#Packet_loss packet loss] multiplied by 100 and  
divided by the [NDTTestMethodology#Total_test_time_in_seconds total test  
time in seconds] *is greater than 15*
  * The proportion of the cumulative time spent in the 'Congestion Limited'  
state to the total test time divided by the total test time in seconds *is  
greater than 0.6* (*WARNING: this condition cannot be met*)
  * The proportion of the number of multiplicative downward congestion  
window adjustments to the total number of segments sent *is less than 1%*
  * The maximum slow start threshold, excluding the initial value, *is  
greater than 0*
