Hey Jimmy, we are in the midst of making a website where we can update the numbers in the charts (i.e., transfer numbers for schools). That information may change year to year. For example, I went to the University of Florida which was not traditionally considered a "transfer friendly school," however, now they are. So trends like that are important to look at. As for the substantive writing of the book, we do have ideas for a second edition, but that information in particular does not change year to year as much.
If you private message me, I'll send you a copy of the book. It is also available on Amazon.com for around $12 right now.
Cheers,
Andrew
