There's a post up now that asks whether we get to keep the app after the challenge, and Marty said only if you are an unlimited member. Guess I'll keep using the spreadsheet.

However, it appears that the values entered in one tab don't populate into the next tab so it looks like you have to constantly copy the values over or track them on multiple tabs.

Or, once you get to the Hunger Training, for example, do you change the "start" date to the date you start that phase? I suppose this, too, will be answered during the challenge. I just don't want to get too far behind in case I have to enter in multiple places.
