When results are unbelievable, the experiment is 
likely bad.  

Most assuredly your s-meter is NOT 6dB per S-unit.  
More likely around 3dB.  And not "linear" (oxymoron) 
either, being probably less than 3dB near S1 and more 
than 3dB near S9.

Try using the built-in step attenuator to check the s-
meter.  It's likely to be far more accurate.
