I do know how you feel.
I have scales at home, scales that I weigh in at Kate Morgan, and scales that I weigh in with with my personal trainer.
I have numbers jingling round in my head as they are all different!
My ticker below and my "constant" reference is my HOME scales. I weigh in on them weekly and enter in that figure into my ticker and jot it down.
And I weigh in at Kate Morgan fortnightly and they write it down on a wee card for me.
And I weigh in weekly (at night) with my trainer, and that gets written down with her.
The amount lost is the same.........
