In my opinion, reloading scales don't need to be .1 or even .2 grains "accurate", but they must be repeatable.. If I weigh a known weigh standard, it really doesn't matter if it reads .2 grains off the known laboratory weight as I don't load near maximum charges, but it must weigh the same every time, no variations. I always start my reloads with book starting loads and work up. If a charge works well with my reading of 9.9 grains, it really doesn't matter if the actual "laboratory" weight is 10.0 or 9.8 as long as the scale measures the same every time...
