I prefer having nominal intermediate states just for debugging purposes. "What am I doing now? Does being in START imply it's already started the process? Does being in RUNNING imply the process was completed successfully?" vs "What am I doing now? In motion!" In the example given, I'd probably stick to a single intermediate state and let the language work as my implicit state machine for the internals. Depends a lot on the boilerplate required to insert states though, my preferences owe a lot to the HFSM implementations I've used in the past.
