I was disappointed not to be informed of the experimental method. Did he normalize the data for each time period? (Dollars/Person within 20 feet), or is it unnormalized and we could just be looking at a situation where more people came later. How long were the time periods of each trial? How much better did he do at each trial, in terms of percentages? Also, since he apparently has the data, I'm dieing to know how much one of these guys does make per day.
