I've kept a small (2 to 3 ounce) starter going for 9 years and counting using a similar method. It started life as a full-size starter (from Reinhart's BBA, I think), and I've gradually decreased the amount of reserve to a small jar. I just used it in the sourdough semolina bread recipe from Jeffrey Hamelman's Bread book.
