I deal with variations in paper response type to type with the masters. So far I have found that they all work about the same amount dailled in to get a certain effect once you get the basic filtration set.

Different films have different base colours. Chemistry varies in how it acts on the print as it ages. These are places where the color star shines for me, allowing me to quickly hone in after months away from the darkroom. If I printed colur every day I may not need an analyser, but I don't think the Colorstar would hurt even then.
