That's it, John. And, yes, you can still achieve anti-squat.
Many of those who post here have mentioned that they own a copy of the Millikens' "Race Car Vehicle Dynamics." There is a companion book for RCVD, a student workbook. As you might imagine, RCVD is often used as a college text. I used it when I taught a graduate level engineering course in vehicle dynamics. This workbook includes contributions by myself and a Norman Smith, who was employed by Jaguar at the time of the C-Type development. Mr. Smith provides the setup equations for equal tire loading and explains, also, that much of the suspension work was empirical in nature, which would account for the multiple adjustment holes you describe. My contribution was to take Jaguar's work a step further and provide equations that would allow both equal tire loading and no squat or rise on acceleration.
Unfortunately, the student workbooks first published did not contain the answers to the questions posed. These were reserved for a "teacher's copy," which was published in very limited quantities. Now, however, when you order the student workbook (more correctly, "Race Car Vehicle Dynamics; Problems, Answers, and Experiments"

, the answers are included and errata corrected. Unfortunately, my note to the Millikens for the addition of a multiplier, to my equation, to account for unsprung weight, did not make it into print. The final term of my equation, at the bottom of page 204, should be multiplied by M/(M-m), where M is the sprung mass and m the unsprung.
I strongly recommend the purchase of both books. (No, I don't make a penny out of this.)
