N2D, yes, you can have your specs correct, but the draw weight and DL be off. This was exactly what happened to me when I replaced mine. It is far more important to be able to hit maximum draw weight and the correct draw length than to have your ATA and BH exactly to spec. Bowtech, and most manufacturers have a + -of 1/4" on specs. So, if you have a bow that lists with specs of 34" ATA and 7" BH. It is within spec if its 33 3/4" and 6 3/4", or a quarter inch longer than list spec.

Once I twisted my cables to length under 100lbs of tension and put them on the bow, my ATA and BH were within 1/8" and I got 70.4lbs on my scale. Draw length was about 1/8" long by my measurements, but felt almost perfect. I left it at that and tuned it from there.
