I have ONE of the same problems with a Cabella's digital scale: it won't respond to trickling on tenths of a grain. I have to pick up the pan and put it down again to get a correct reading. I don't know whether that happens with other digital scales, because I don't have any others to try. Also, I can vary the weight by 0.1 to 0.2 grains by putting the pan off-center on the weight table.
BUT, my scale always shows zero when I put the empty pan back down on it. So, maybe your scale does have a problem, since it seems to loose zero. (I am assuming that you push the zero button with an empty pan on the scale after letting it warm up for about 3 minutes, before you start loading.)
