It depends. If I'm just starting work and I have a reasonable negative, I can usually get an acceptable - not good - print in three or less tries. Continuing with similar negatives, I can often get a decent print in one try. (I cheat and use an on easel photometer to do that.) To get a good print often takes me a quite a bit longer. But not always. It depends on the amount of manipulation required, the sort of things that need to be done, how well my eyes are calibrated at the moment, whether there really is a good print in that negative, how clumsy I am, and a whole lot of other things. With a good negative, a good print comes pretty easily.
