Yep.

Like rob said the post setting sets letoff. With your DP2 module and draw stop setting of 7 you should be close to 29". From there you can make small adjustments (Very small) to the draw stop to increase/decrease letoff and make small DL adjustments.

If it feels short your string or cable lengths may be out of whack causing the DL to be off. Best way to check is to measure the actual DL at a bow shop so that you can be sure that all is well.
