Strange that nobody on this thread seems to have mentioned this yet, but if you look thru` SMR`s website, www.smr.com , there is a free link to "Mr. Goslin`s IFT Point System" which appears to explain the same system as referred to in the book.
To those who have read the book, can I ask if there is any substantive difference in the systems?
