 The number of research papers that a scientist can write in a year depends on many factors, including their research focus, the amount of time they have available to devote to writing, and the complexity of the research being conducted. Some scientists may write several papers in a year, while others may write only one or two. In general, scientists who are actively conducting research and publishing their findings can be expected to write several papers per year, not a paper every week. In addition, scientists who are also teaching or working on administrative tasks may have less time available for writing papers.
It is also important to note that the quality of research papers is more important than the quantity. A scientist who produces a few well-written, high-impact papers may have a greater impact on their field than a scientist who produces a larger number of papers of lower quality.
This study further investigates most prolific authors who have written a paper solely him/herself. Table 2 presents the results. What is more amazing that these authors are all from Clinical Medicine abd can single-handedly write over 72 papers per year. But  most of these authors are journalists from BMJ and other news outlets. The exception is Viroj Wiwanitkit from Dr. D. Y. Patil Vidyapeeth, a University in Pune who published, on average, 74 papers per year, and Romina Brignardello-Petersen from McMaster University, Canada who published 53 papers per year.
This result highlights the deeply fundamental flaw of the so-called “databases of standardized citation indicators” which do not recognize if an author is a journalist and the articles are news articles [3]. This standardized indicator place value on single-authored and first-author papers made a journalist Elisabeth Mahase who can write a one-page news article every two days has a c rank of #33363, much higher than scientists from MIT, Stanford or any scientist that had to do hard work in experimental research. Journalist Bridget M. Kuehn, according to the Stanford list, is ranked #17026, much higher than 2021 2021 Nobel laureatte in Medicine Ardem Patapoutian who has a c rank #28519, and 2022 Nobel Prize winner in physics Alain Aspect, who is ranked #20486. This c rank can be easily misused.
