I had a bag of salad croutons that measured a serving as “2 Tablespoons” — are they expecting me to crush the croutons to measure a serving? Or just “eyeball” it to convert rectangular things into hemispherical things?
It's worse than that. The serving size changes the resulting label. A lot of the high-protein breads have the same composition and are sliced slightly thicker to hit the 3.5g mark so they can round up to 4g per slice and appear to be more protein rich in composition.
