My wife had a doctor's appt this morning so I went with her and after they weighed her I asked if I could use their scale and they said OK. I weighed 204.8. This was at about 10am after I had had breakfast and was dressed in my New Balance Walkers, Jean shorts, Tank Top, socks, with my wallet, flip phone, car keys, and a quarter, dime, nickel, and three pennies in my pocket. Then when I got home and stepped on my scale with the same stuff the needle stopped just a shade past the 205 mark. So I feel pretty good about the accuracy of my scale.
Did you check for lint balls in your pockets? They tend to add a few pounds just like a camera.
