Hi disfan0705,
I wrote the computer software the Unofficial Guide uses to create its touring plans. While I enjoy the Passporter's features as an organizer, I'm pretty sure even the Passporter folks will admit that their touring plans do not save as much time standing in line as the Unofficial Guide's. (The Guide's touring plans are generally within 2% of optimal.)
For what it's worth, the computer software the Guide uses came about through my Masters (and now Ph.D.) research into solving certain kinds of scheduling problems. Details on early versions of the software have been published in peer-reviewed academic journals.
The Guide also employs teams of data collectors who measure the wait time at every attraction, FASTPASS booth and restaurant from park opening until park closing, several times per year. We employ a professional statistician to analyze those data before feeding them to the computer software. After the software recommends a specific touring plan, we do live tests with real families in the parks to make sure they work.
To the best of my knowledge, no other Disney guidebook does anything remotely like this. My guess is that most other authors sit down with a pencil and a piece of paper and try to figure it out. Given the literally billions and billions of possible combinations for any non-trivial touring plan, I doubt seriously any human being could match the number-crunching power of a computer.
Hope this helps. If you have any other questions on the touring plans, feel free to drop me a line:
