I would add that, what resonated with me, from Nancy's comment, was the adverb, "consistently." I believe that high level of workmanship accompanied by the ability to achieve it consistently, produces an advanced quilter. On the other hand, you could say that consistency (which comes from a lot of practice) is what is responsible for a high level of workmanship. I suppose, then, the next question might be, how is that different from a "master quilter" or some label that defines a quilter whose skills go beyond that of an advanced quilter? In the end, all things are relative and bounded by a commonly accepted definition over time...
