Indeed. Other duties is taking its toll.

The big difference is that Peter used another GPS clock as reference. By that
he is actually doing a delta measurement between the receivers. Hooking the
3325 up to a Cesium would be a much more interesting measurement.

You would like to query the receiver in a different maner, so that would
require a modified firmware.

Wait for the sunspot high-season before anouncing something like that! ;)
