Oh! :)

It seems I'd completely miscalculated my 10% goal. I don't know what I'd done to work it out as 10st 10lbs, but it is in fact the first two digits of of your start weight in pounds. My start weight was 175.5lbs, so my 10% goal was to lose 17lbs, or to reach 11st 4lbs. I did that yesterday, so I've reached my 10% :D I'll get a keyring and everything.
