hi,
As a recovered scale addict, I can tell you that it varies from person to person. At my worst I was weighing up to 13-15 times a day! I now weigh every several days or so in the morning. I think CAD has you weigh everyday and then average out the total, I just see what the scale says and if I am down and maintain it for more than 4 days then I change my stats.

cheers,
