[time-nuts] Phase accuracy of multiple output frequency picDIV

While doing some tests using a pd16 (5/10 MHz to 1,10,100,1000 Hz 
output) I noticed the 10 and 100 Hz outputs seemed to do a small phase 
shift every 5 counts
I measured 400 ps shift every 5 counts for the 10 Hz output and about 
800 ps shift every 5 counts for the 100 Hz output.
To verify the test setup I used a pd05 (10 MHz to 100 Hz) and this did 
not show the phase shift every 5 counts.
Is this phase shift to be expected from all multiple output frequency 
picDIV's ?
Erik.
