New bow? If the drawlength is matched to your physic one of the first things you need to do is take measuements such as brace height, poundage, A2A, and such.

To measure tiller accurately there are two accepted methods. One is to bottom both limb bolts and back them out evenly until the accepted poundage is achieved. The other is to stretch a pice of string from axle to axle and measure to this string, not the shooting string. Record this measuement for future reference also. It doesn't matter what reference point on the riser you use so long as you use the same one all the time.

Now, take a pencil and mark the side of the cams where they pass through the limb slots. Every so often check these to assure thaat the rigging is not creeping. With your factory strings it probably will. Although Hoyt makes fine bows, be it Hoyt or Reflex they are notorious for having mediocre strings. If you notice changes in the bow as time goes on this will most likely be the culprit. If and when you want to replace the strings I would opt for a good set of aftermarket ones that are prestretched, which will minimize creeping. I replace mine right from the git-go.

With good strings on the bow you can shoot as little as 20 shots to settle the strings into the cams and get rid of initial creep. Take your necessary measurements for future reference and pretty much rest assured that the bow won't change much over the life of those strings.
