[ntp:questions] Loop Filter Gains vs. Polling Interval

Can anyone tell me, does the sensitivity for frequency adjustment lessen
as the polling interval increases?  I ask because I'm observing that my
offset increases and the frequency adjustment decreases to the point I
fall out of sync at polling intervals above 256.  What am I doing wrong?
