I think daily is too much for everyone to make a predict (myself always late trying to post before deadline), should make it once per 3day or make it weekly again so participant has much more time to post their guesses
Yeah you've got some points. I think Once a week is good enough. There are not so many matches in one day (weekday). So, the prediction range become narrow. I guess some people didn't want to join the prediction because they have the same prediction with someone who has posted before him. (Maybe)
