Disgusting is a hard word, perhaps I should say: "funny".

However: Simply not realistic.

That's not an ns2 problem. It's simply extremely hard to provide a sound 
CSMA/CA simulation.

Honestly: I'm not fully convinced that a convincing CSMA/CA simulation 
is possible at all. This is particularly a question to communication 

I don't mind estimating a possible throughput on a rough average basis 
as a "rule of thumb" in a particular simulation.

However, we must not take those long term averages as a justification to 
predict or to simulate the link/network behaviour for individual packets 
with a time resolution in the area of milliseconds or less.
