Dear Heather:

Actually, I will repeat what I said in a more lengthy post.  The neonatologists concluded that 
the scale WAS accurate and I looked at the details and that's exactly what their data 
showed. 

And no, I have not seen the scale give an inaccurate reading, unless an article of clothing 
was removed or the scale was sitting on an unstable surface.  And that is NOT 
measurement error, it is observer error for not using the scale properly.

What the authors incorrectly assumed was that it was imprecise, which they did not show 
because precision requires repeat measurements.  And in fact, the scale is far more precise 
than eyeballing bottles.  But eyeballing bottles is far more precise than I suspected.

Best, Susan
