I use the term "refreshed starter" and I presume this is the condition you are inquiring about. When I use the term, it means that the starter is ready for use, that is the yeast and the lactobacteria are fully active. Depending upon the hydration of the starter, it may have risen to nearly the max or even started to fall. With 100%, or more, hydration, this is sometimes not easily determined. Don't worry overly much about the exact timing it is not that important. It is only important that the micro-organisms are fully active.
