The nutrition facts indicates (1 cup = 127 grams) so taking your average of 36 grams, are getting a little more than 1/4 cup with your scooping method. Specifically you are getting 36/177 cups which equals (1/4 cup + 1/30 cup + 1/7620 cup).
I do not know if this will be helpful to anyone besides my own curiosity, but I had access to some dry scoops so I thought to investigate this the scoop is “1/4 cup” claim.
Disclaimer: dry measurements are hard, which is why the most accurate way to do recipes and get consistent results is by weight (even though that method is not popular here in the US). I have known this for a long time, but looking into the Huel scoop, I now understand it. Huel is not at fault at all for dry measurement of its powder being somewhat imprecise.
Transferring from one dry scoop (or measuring up) to another was terribly imprecise because in the transfer I lost compaction. In fact, I could not make 1 Huel scoop fit in either a 1/4 c or a 1/3 c dry measure. But nor could I make them fit in the Huel scoop going the other way around.
Switching to liquid, I found that the Huel scoop more closely matches the volume of my 1/3 cup measure. (After i did this, I noticed that all the measures I used has a liquid marking as well (1/4c = 59.1ml, Huel Scoop = 70ml, 1/3c = 80ml. However, the Huel scoop has a more narrow opening so probably had different compaction characteristics, so it still could be a true 1/4 cup dry measure.
I keep a plastic knife in my bag and use the “dip and sweep” method. Since the scoop is transparent, I notice that I often times have a corner of the scoop that is absent powder, so do a single stab the knife to break it up enough that it falls in. If I didn’t do that, I would probably be closer to 1/4 cup. As is, I am pretty sure I get a bit more than 1/4 cup per scoop.
My opinion: depending on your scooping method, the Huel scoop is somewhere between 1/4 and 1/3 cup. If you are using more traditional measuring cups, I would agree that someone doing a quick/imprecise scooping of Huel is probably closer to 1/4 cup, but for some scooping methods 1/3 cup might be closer.
