I should mention this. While I was in Engineering school and we had some lab experiments with electronic components I learn the chips/resistors/capacitors etc etc com in two groups. One group contains a sensitivity of 10% tolerance (that is +/- 10% for resistance of a resistor, So that means if a resistor is listed as having 1K ohms...it is actually 900 to 1100 ohms.)
Military applications have greater control over sensitivity for obvious reason. For example a BkackHawk helicopter communication device needs to have less sensitivity so not to misroute communications or landing. Military sensitivity tends to be up there in the 1% range. These type of components are not found typically at Radio Shack. Lol...
Now how does this apply to your electronic scale? I am guessing the brand of your scale is not made with extreme tolerance. This is my guess...but also probably other factors come in play like atomspheric pressure, density of air and water in air...ans the fact that after one day maybe the powder just weights less cuz it feels like it hehe.
This is all my guess. Bt hey lets not get too worked up over this...
