| Scale uses mass, which along with gravity (acceleration) is the force (weight). So a scale upside down then reads what?
I'd agree, not seeing how this is any more precise. It could be said it's more accurate - but that's like back to the day of the dart board in class. all three darts clustered together around a single number (double 3 for example) is accuracy. precise is having them hit the intended target - say for example the double bullseye. Only one dart would have to hit it, and the other two on the 14 and the 5 for example, would already be more precise than all three clustered.
It all comes down to how calibrate the yield sensor.
