Digital Scales

Linearity probably ain't gonna be a problem weighing power charges with a 100 gram scale.
You are NEAR a calibration point- ZERO.

One advantage of a 0.02 Grain resolution scale over one with higher resolution is you don't get in between readings when sorting primers into 0.02 grain bins.
You know, like getting a 3.645, 3.650, or 3.655 right between 3.64 and 3.66.

I don't think I'm delusional to hope for .02 accuracy.

Just a note. All scales are subject to drift. You will not see it if less than the scale resolution. On an Fx-120 that could be 0.019 gr.(0.02 gr resolution). Also scale drift is a zero/tare error. It is not a calibration error.

Absolute accuracy is immaterial if only one scale is being used. What matters is the repeatability and resolution of the scale. We do not have to consider the linearity. The repeatability of the Fx120i is 0.001 gram (standard deviation). In normal terms that is 0.002 grams( 2SD) for 95%. The combined resolution 0.002x15.432 +0.02 or 0.05 grains.

Cool I have been trying to get myself to buy the fx300i and even at that good price right now I'm still having trouble justifying it I have something I think I can do .02 accuracy but am having trouble trusting it just yet.
With the fx300i ican add the auto throw and trickle later.

Harrells powder measure, drop into glass cup put on FX120i scale trickle up with V3 electronics coupled to Ingenuity trickler. Fast and accurate!!!!!
