Smells Shiggy to me
Going by weight is the right way if your rub is figured in Volumetric measure, doing it this way ensures consistency. I tend to do my rubs in PARTS because a PART can be anythhing a LB, a 1/4 tsp or a shot glass just don't matter doing it in this manner it is easy to consistently mix any amount I want accurately.
