I'm pretty sure I was reading the scale incorrectly. Calle does not weight 1.2 kilograms; I think I've got a more accurate reading this week. This week's weights in the extended entry.
Metro 800 g no change
Kono 820 g no change
Calle 1020 g change, but that's due to my misreading last week
Olie 880 g no change
Witter 820 g +10, but on last week's note, I have it bouncing around. First I wrote 810, then 820.
