From my understanding R79 simply allows for the sampling of the output voltage for the self calibration feature and is only used when the calibration cycle is running.
Indeed they do lock out frequencies above 1mhz when the larger resistors are used but we are talking about sub 100hz signals in this case and only looking for a rough estimation of actual in circuit behavior to decide if there is merit in actually lashing it up. If the transformer doesn't meet the desired low frequency results with a 5K series resistor there isn't a chance it will do better when it is loading a 10.
Applying rationale that may be extremely important in the megahertz+ range to this situation is probably not the best use of anyones time here.
