Definition of Erratic

Me on a diet! Top line is the target set, 1lb a week for 13 weeks, leading up to the holiday. 
Line below that is Carl's who has steadily followed the designated path.
Zig zag below that is me! Still lost the weight, and a bit more, but certainly not smoothly!
Busy packing and sorting so little time to blip, but hopefully will be able to post a few pics of the Florida Sunshine while we are away!
