I had a new string and cables installed about 5 years ago. Shot about 100 times and have not shot since.
Not a problem. Strings wear out from the same thing everything else does, cumulative stress. Heavy bows wear out strings and cables faster than bows of lower peak weight, light arrows are tougher on rigging than heavy arrows as the energy that doesn't go with the arrow, is contained by the string and cables, That Newton/Einstein thing.
I shoot year round with my collection of six bows, 50lb and 60lb, and I swap out rigging every 3 years. Even with six bows, that's a moderate amount of stress, and I haven't had but one failure in about 30 years of modern strings and cables. When the bow is at rest, stress is minimal, i.e. your rigging is about 100 shots old.
