Selzer is very convincing about his research of Nelson's research, and that is due to the fact that his knowledge of Nelson's writing habits is so extensive. He proved many times that he had studied Nelson's style and observed his work and writing. One way that he proved that he had studied Nelson's work was to mention how Nelson would reuse information from past reports and writings. Another form of proof is that he knew Nelson's writing style so could safely say how he used contractions, personal pronouns and formed sentences. Selzer also fully understood Nelson's revision method and knew approximately how long it would take to write, revise, and have typed the report that he was working on. Such extensive knowledge of Nelson's writing style can only suggest that he spent time carefully studying and observing Nelson so that he could understand his writing style.
