Recalibrating

The new scale has arrived!  It doesn't have all the bells and whistles of my old one, but it has a very wide base which will help with accuracy, and it is new and factory calibrated, so I know it is (more) accurate than my current scale.  Here is the old one:

And here is the new one:

An unfortunate reality is that my current scale is inaccurate in the wrong direction.  I opened up the new scale and weighed myself on both and the new scale was 5.4 pounds heavier.  I was 384 on the old and 389.4 on the new.  Now, I have been weighing myself on the same scale the whole time so this does not change how much I have lost, just where I started and where I am now.  I will do a couple more calibrations to get an average difference, and then I will adjust my previous numbers to match.  So far I am break even for the week (though I weighed later today than usual), so that should make things a little easier.
