Not what I meant I guess. Sure, it can be measured without a spring in place and compressing the suspension will give you a measurement of what it will be at a specific ride height. However, dynamic camber is MUCH different when you start to turn the wheel as caster and SAI play into the amount of dynamic camber that is added to the wheel. One could setup a scenario where multiple points are measured, but to get an accurate idea of what the suspension is doing under load many points would need to be measured.
Alternatively, one could measure all suspension components and plug the numbers into suspension modeling software to determine all values....I don't have that.
