I would disagree that none of those conditions were met. One could say the posting of the graph transformed the conversation from one of "go read this" to a graphic example of what needs to be achieved. Part of commentary in the discussion to direct the OP to a document that would assist in his goals. Removing the graph and additional commentary, we are left with the references below to Mike Martin's work without divulging the entirety of the chapter contents or methods, thus providing limited purpose. As such, the OP will need to do additional research on the topic, which may lead them to a search for this or any of the other books mentioned in the thread as the OP says he now has some reading to do. So I'd say we fell within fair use guide lines as described in the definition above.
Another easy answer is simply set your car up to fall on the neutral handling line as shown below from the Mike Martin book, Mopar Suspensions.
Its all the calculations that go into figuring out roll couple front and rear that make it tricky. Martin's book gives info on how to do this, as do the other books listed above and the Mopar Chassis and Oval Track books also have info on it.
