I think messsing with the strap lengths is a bad idea unless you want to spend the time mapping out the arcs as described. If you are going to do that you also need to map the side to side movement of the rear end created by the rear arm/radius rod configuration so you can match the arc of the ladder to it. Which holes the radius rods are in will change the side to side movement of the rear end as well.
Also, the side to side movement is slightly different in roll than it is in bounce.

Maybe that is why the mount spacing (14"), strap length (7") and spacing of the straps on the ladder (7") have stayed the same for so many years. It is a good compromise for all conditions based on current tube heights, arm lengths/angles and radius rod lengths/locations/angles.

Man, time to quit cause I'm starting to sound like LarryO.

There was a very good article on this in an old edition of Open Wheel. I have it somewhere, but am too lazy to dig for it right now.
