R-0870 - Do you use a full scoop?

So when I test for Cl, I don't really need a "heaping" scoop of R0870 powder to get a stable color of pink, and from my tests I can't tell a difference in the results - admittedly I haven't run a good experiment to validate that, but if someone already has then no need. Anyone else use just enough to get the water to turn a stable color (pink or red depending on ppm) and/or experimented to see if there's a difference in your results based on just enough vs more than enough powder?
