You may have experienced worse than normal speed loss because you did so little film. In large volume, the developer has less chance of dying from age because it is being replenished all day long every day. Doing only a few films a week, the developer may be losing strength from aging.

The usual speed loss from replenished systems is 1/3 to 1/2 stop. I've never known a lab to warn customers of it, probably because most people wouldn't notice it unless they were perfectionists like me.
