I would guess that three pounds difference between scales really isn't that much to some people. But not us As long as they both give concistance numbers, no matter what there are I think using either is good. Personally I would chose the one that said I was lighter!

We replaced our digital scale not long ago because there was a 5.5 pound difference between it and the doctors, and gym scales. AND not in a good way. To be honest I rest my starting weight. But it sure felt good knowing I weighted 5 and a half pounds lighter than I thought!
