To be honest I've read so much on the subject that I'm a little bored of it.
What you're saying is that Ackerman (in a practical application) is not constant throughout the steering swing. This makes sense sure but I did previously believe that it could be measured at a static steering angle.
If it's variable throughout the range (and I'm happy to accept it is) then I can't for the life of me imagine how you'd measure it without special equipment!
My head's going to explode. I'm glad I didn't need to understand the theory to determine the answer to my quest! lol.
