Unfortunately a lot of medical science involving expensive laboratory resources and trials currently rests on sample sizes around this range (~5-20). Then whenever there's any kind of technical innovations that makes it cheaper to collect the biosignals there is a sudden series of breakthroughs in what is really happening. All science is a work in progress.
