[time-nuts] PRS10 calibration

I have been digging through the TN archives and came across a post dated 
May 2, 2012 having to do with the calibration of the PRS10 RFS.

In reading this it appears to be a process of stepping through the 
various time constant (PT) values during the discipline process and 
monitoring the time tag values being as close to 0ns for ideal results.

My questions are these:

  * Is there a quicker way to individually step through the PT values
    and is it possible to use every other PT value when calibrating?
    When all is said and done a total of 61+ cumulative hours is
    required given the expiration of each natural time constant setting.
  * Should the time offset value (TO) also be adjusted in conjunction
    with each successive increment of the time constant?
  * Are there any other adjustments to be made during the calibration
    process?

Thanks,

Chris
