OK its a pretty good read, like he said, "It should be clearly understood that neither of the subjects was an "average" subject, and there is no implication that subjects of average or below average potential will all produce equal results from a similar program of exercises." The first thing you should do is ask yourself what has the person to gain..I can't really see any advertisements or anything subtle like that..
Another interesting point:
For example, during the first l4 days, Viator gained 28.93 pounds, a daily average of 2.06 pounds. During the next 3 days, he gained 3.92 pounds, a daily average of 1.3 pounds. During the following 5 days, he gained 6.09 pounds, a daily average of 1.2 pounds. And during the final 6 days, he gained 6.34 Pounds, a daily average of 1.05 pounds.
So it is clear that his "rate of gaining was slowing down at the end of the experiment . . . but it is equally clear that his actual growth was very steady.
Thanks
