I agree that *you* have over simplified the grounding and thermal
trade off issues.  Your implication that I have over simplified the
grounding and thermal trade off issues is total nonsense on your part
as evidenced by the successful QS1R design.  I took those issues very
seriously and that is why the LTC2208 runs ~20 C cooler on QS1R.  It
appears that less thought went into the Mercury PCB design.

Was any testing done in manufacturing to document a range of normal
temperature values for the Mercury's LTC2208?
