Two scales is not enough assurance. You need three.
You also need to triple-weigh your beans after grinding.
Maybe they’re using a similar system to O2 sensors in SCUBA rebreathers. 3 identical sensors measure the same thing. When one sensor drifts, the computer uses the value from the 2 concurring sensors, and throws an error to let you know something is wrong.
That system is life-critical, so these beans must be about the same importance.
