If you look at the binary of the word that goes into a DDS adder, the ones with more low order bits have closer in spurs. Think of that word as a fraction, binary point on the left rather than right. If your adder word is 0.001 (binary) it will divide by 8, no spurs. If you have 0.00100001, it will divide by a little less than 8 and have spurs. -- These are my opinions.
