It's hard to say what the D.B.A.N. is today. The first 6 times I got on the scales this morning it read 278. Then it read 282 five times in a row. I could split the difference and call it 280, but I'll stick with 282 for now. My scales at home are electronic and fairly old, so they seem to be wildly inaccurate at times. I'll be researching this and getting back to my faithful readers soon.
