If you are talking about absolute frequency accuracy, remember that
the Windows RCT is only as accurate as the source used to calibrate it.
And from what I understand, the RCT is field calibrated against a
little quartz tone reference/metronome that costs a lot less than
$200.  That's the device whose accuracy you should be evaluating.
