I'm not sure how much of a concern it is to have people join the team last minute. The scores between the two groups have been fairly close together, and if enough people jump on whoever is winning at the last minute, they could make that team lose from the sheer volume of deadweight ruining the average. That would be a bit funny, though. Perhaps they can close off people from joining 24 hours in advance.
But in general, I think the page is fairly easy to read, and that this seems a bit like... complaining simply because one team is currently not in the lead? As I said, though, the scores have been really close together throughout most of the fight, and sometimes Dolly is in the lead and sometimes Tobias is in the lead. I'm not sure bolding one number on the page is really going to make or break who wins.
