But if you can fight in another round every 30 or 60 minutes, surely the person with the most time on his/her hands will have a clear advantage? So someone who works more often than another person will be unable to make use of multiple rounds in a day.
I'm assuming it's the better nations who fight in the most rounds that actually have a better chance of winning?
i.e. wouldn't, let's say, a 'retired' person have a significant advantage over someone who works and commutes 15 hours a day?
