A Subtle Accuracy Problem: Zero Drift

This is my first review on Amazon. I bought this scale because of the good reviews and because it was America's Test Kitchen's #1 choice. I really like almost everything about it. However, I may have found a bug and I have a feeling it would be easy for the manufacturer to fix the software bug. I contend it will override "zero" without you pressing the tare function, on the fly if your weight changes very subtly. The video below, in which I place a few grams of yeast in two identical scales, is intended to demonstrate this. Things to note before viewing: 1. These are identical, new scales. One of them looks blue because I left some tape on it to tell them apart. 2. I am not suggesting that any of them are broken. I can get both scales to behave the same.3. After you see me tare both scales in the beginning, I will never tare again. Be patient, I need time to put the weight on the right scale. You have to do it gradually to see this effect. Note that the left scale doesn't show the same behavior since I'm adding the weight all at once. Again, I assert that it overwrites null itself, and it will continue to do so until it detects changes. Tech note: I have a feeling that the redefinition of null along with mismatches in variable precision (integer, float, or double) somewhere may contribute to internal rounding errors in the for loop. I don't think it's a hardware issue as a quick release will always show the correct delta weight.

Pros
