100% is complete anal perfection which as we know is also a complete 100% chronic stress condition which effectively negates any benefits of the primal concepts.
The optimal goal is 100% in all primal areas including diet, exercise, daily movement, stress reduction, fun, mental stimulation, social engagement, etc., all the while knowing that realistically there are compromises to be made and even within the primal sphere some of the goals may be competing, so you find a healthy balance somewhere less than 100%, only you can judge what that is.
A primal couple fully in agreement will have a different ideal set point to say a mother of 5 non primal kids and non conforming husband.
The healthiest point is the place that gives the greatest nutrition for the lowest degree of stress, this point will be different for each individual, so arbitary measures become irrelevant.
