That's the approach of a business manager, or a public relations 
manager, or an attorney defending a guilty client, but it's NOT good 
science. Science in this case happens in the lab where the actual 
performance of rigs is MEASURED under controlled conditions that are 
representative of operating conditions. Some measurements can also be 
done with spectrum analyzers looking at the signals from transmitter on 
the air. See my link of a day or so ago to the presentation on clean 
signals.
