 The client link duplex mismatch heuristic does not work with multiple  
simultaneous tests. In order to enable this heuristic, the multi-test mode  
must be disabled (so the `-m, --multiple` options cannot be set).

-<font color="red">NDT does not appear to implement the heuristic  
correctly.</font> The condition "The link type detected by the  
[NDTTestMethodology#Link_Type_Detection_Heuristics Link Type Detection  
Heuristics] is not a wireless link" is always fulfilled, because the Duplex  
Mismatch Detection heuristic is run before the Link Type Detection  
heuristic.

Mismatch Detection heuristic is run before the Link Type Detection  
heuristic. Also, the condition "The Theoretical Maximum Throughput over  
this link is less than 2 Mbps" does not appear to be handled correctly  
since the [NDTTestMethodology#Theoretical_Maximum_Throughput Theoretical  
Maximum Throughput] is calculated in Mibps not Mbps.

 The difference between the Server-To-Client throughput (> 50 Mbps) and the  
[NDTTestMethodology#Total_Send_Throughput Total Send Throughput] (< 5 Mbps)  
is incredibly big, so it looks like a bug in the formula.
