String Life

When to replace?  Mine shows very minor wear just below the serving of my D loop. I keep it waxed and do not carry my bow by the string while hunting. Just curious I guess.

I wouldn't worry about it.

If it's just the serving then yeah, don't worry about it.  The serving is there to protect the string.  Your actual sting should be fine. 

Back in the day before D loops it was common to replace the center serving several times before you needed to replace the string.

General rule of thumb is 2 years. If you notice any fraying on the main strings, get them replaced.

If you notice any of the single strings cut or in 2, don't shoot your bow anymore before you get new ones.

Generally serving around the cams and center will start to come apart or shift. You will start to notice your tune starting to get out of whack.

If you learn or are able to re-serve, that will save you another year or so maybe. Strings now a days are really good, but servings won't can can't last that long.
