If I take out 35.7, the SD drops to 0.50 grains. If I replace it with 38.7, the SD becomes 0.48 grains. The means are 38.49 and 38.51, respectively. The ES in both instances is 1.4 grains or 3.64%.

Everyone who has worked with the scoops knows it takes some practice to use them repeatably. When you first try measuring throws from them, you quickly appreciate how well powder measures actually do.
