You will still have a min and max, they will just be equally dispersed. So if you have a profile measurement of 0.010, your min will be -0.005 and your max will be 0.005, for example.

Here is what i don’t understand, if you you dont have a datum, which means that there is no actual nominal distance of any kind, there for the profile can be anywhere even an inch from the nom, as long as the profile is good to itself . Unless i am not understanding this correctly and regardless of whether there is a datum or not, the profile is still evaluated in both directions from the nominal.
Junkie, if it was flat yes, but what if the surface is nit flat, its a curve or a radius.
