5% error? A 150 lb human who used a scale that could be 7.5lb off would call that scale useless.
"The camera adds ten pounds" has become a legitimate excuse.
They might.
They might be wrong though since the error is probably not random but relatively consistent.
So it wouldn't be an ideal scale to measure mass, but could still be a useful tool to measure weight gain or loss.
I wouldn't expect it to be consistent without their saying something about it. It seems difficult. Why not just put a scale in the mouse cage, with a food pellet on it? Mouse climbs onto the scale and you take a reading.
