Thanks, Sandra. I just use the one set of scales in my bathroom so, although I can't guarantee that they're accurate, at least, if they show LESS this week than last, I know I've had some success. Hadn't thought of putting a magnifying glass over the scale - will try it next week (or put my specs on as, irritatingly, I hadn't thought of doing that!).

Thanks, Patty - congratulations to you too!
