ADF4350 - Time to reach final frequency greater than ADIsimPLL predicts

ADF4350 - According to ADIsimPLL Report - Frequency Locking:
  Time to lock to 1.00kHz is  430us
  Time to lock to 10.0 Hz is  586us

 

Whereas the time to see the output signal at 2dBm output level on the specrum analyzer is 2.15ms at 3kHz bandwidth and 781us at 3MHz bandwidth. What could explain this variation?
