Wow, that schedule is brutal. Just looking at it from a logistics perspective, these girls are not being afforded a proper opportunity to eat. They're jamming them through a 13-hour marathon with just one 2 hour and 20 minute break for a combined lunch/dinner??
Then many of these girls will be sitting for a couple extra hours afterward each night when making their decisions and marking their cards. I hope they're strongly encouraging snacks inbetween rounds, because just eating one meal in 13+ hours for a few days in a row is not appropriate or healthy.
