I think if you read the manual again you will see that they are talking about a Tiller adjustment.

Single Cam bows can lose time, but it effects your bow in a much different way then a 2 cam bow. As your Mathews loses time you will lose draw weight and speed.

Find a good bow tech and he will be able to show you how to check time on your bow. Its easy, but I don' t think I could describe it in a couple sentances.
