Scoop size for Huel V3 vs Huel Black

Hi, all. I have tried Huel V3 for the first month and now order Huel Black to try for the second month. The Huel Black version did not come with a scoop , as expected, and I am using the scoop from my first order. However, the Huel Black bag is smaller and contains less powder than the original V3 version, while the bag still says it has 17 servings per bag. I wonder how can it be still 17 servings if it has less powder and we are using a scoop of the same size.
