New strings on a single cam bow can be troublesome due to their length and the fact your nock set is not at a center point in the string. If your nock set height was at 3/16" above the rest before chances are you will be 3/16" above now. But that 3/16" on a new string might not stay 3/16" for very long. So I try to get at least 50 if not 100 shots through a new single cam string before I am happy and confident it's going to stay there. Usually don't even bother putting a peep or D-Loop in place until I've got the string shot in well as the peep generally will just twist out of place anyway. Even with strings I make myself to exacting lengths, served under proper tension can sometimes move a little in those first 50 shots. Always better to shoot them in during warm days or in a heated room, but shots period will relax the stresses and binding beneath the servings. If 452X or Xcel 50 shots should be plenty. The new 8190 or XS2 I would give a full 100 shots. Even more if your string builder is one of those crazies that makes a good string but thinks 26 or 28 strands on your cables is somehow going to improve something that 20-24 will not.
In the old days we could get away with hand rubbing a string until it was good and warm to remove molded and served in stresses. The new 100% HMPE materials do not like this at all. They fray under the heat and you can actually create creep that would not have otherwise appeared. SO I no longer recommend rubbing instead of shooting. Plus shooting is more fun anyway. It really is a great chance to do some closed eye muscle memory / form improvement practicing.
