IMO, scales are only good for noticing longer term trends in weight. I would really not bother weighing more than once a day. Really, once a week, and look at the weights over the course of a month or two to get anything meaningful. And, even then, if you are near a healthy weight, you don't necessarily have any information that is useful. You could be working out hard for a month, lose 5 pounds of fat but gain 5 pounds of muscle. A net change of zero, but your dimensions will be different.
I have an unhealthy relationship with the scale, so tend to not want to use it much!
