K3: LPA power level accuracy?

Hello fellow Elecrafters,

Quick question - I've noticed that when using the LPA, output power is
always slightly off compared to the reading given off by two fairly accurate
meters.  For example, a constant carrier output of 5 watts always reads
about a half-watt less on the external meters.  The output power from the
KPA3 however has always been on the dot - 80 watts drive reads 80 on the
meter, 100 watts output reads 100W on the meter, etc. etc.

I'm not really concerned, but was wondering if this was typical?  I've
calibrated several times in the past using the K3 utility, but the results
are usually the same.
