For me, I try to look at the mounting hole and their relationship (distance) to the hinge point. Then its easier to see how much LEVERAGE a certain hole would gain or loose.
If you start at the shock tower mount, then go to the upper hub mount, then to lower hub hinge. then you can see how the upper camber link has leverage on the hub and transfering this to the tire.
Try and picture the chassis roll into the camber link and tranfer that leverage into the hub.

This is just how I look at it, hope it helps others

I understand that the fourth, lower inner hinge has to be taken into consideration, especially during compression as to the total amount of leverage.
Ride height also has a big play with chassis roll.

But mainly like b3master was saying, the track determines how to best apply your leverage
