As mentioned before, Willis S. Jones and associates had this habit of recycling papers the worst way possible. For the discharge measurements, it looks like Mr. Jones was transferring raw data to another set of (medium rare) spreadsheets. However, instead of using a new piece of paper when messing up the numbers (which he did quite often), he just added stuff left, right, up, down, making reading the documents a rather difficult task. Even after typing out the data out on a supposedly clean (well-done) piece of paper, he still penciled in more information. So kids, remember, save all your crap in one place, preferably with backup copies.
