Hi, have just found all of this as I have my 'last supper' of sushi, chocolate and a cinnamon bun washed down with cherry coke (yes I know, but it was good!!). Am I ok to join in a week or 2 late? Have seen the spreadsheet - it's amazing - am learning some of the acronyms (sadly biwi took ages til the penny dropped!!) - what is WOE? And BC? If I just add myself to the spreadsheet and put my weight the same for last week and this, would that be ok?
