Ok, so not nearly as perfect as I had hoped. And I also learned something important today: extreme cold seems to affect digital scales strangely!
Anyway, after my scale warmed up I did an unofficial weigh in so I can return my friends scale and just start using my new one. It seems like my new scale reads me as being 0.4 lbs lighter than my friends scale. I even moved them so they were at the same place in my appartment to keep conditions identical, not that it seemed to help.
I wrote a note on the picture I submitted, but should I email someone as well? Really, I guess, shouldn't my starting weight probably be adjusted by 0.4 lbs to reflect the difference in scales??
