I guess it's a little like sports. Sometimes your team has a big lead and blows it, and sometimes they make an epic comeback and win at the buzzer, and sometimes they dominate from start to finish. Well, rarely do the models show a good storm 7 to 10 days out and it happens, so they rarely dominate. Most of the time it's the other two scenarios, with having a big lead and blowing it at the end happening more often than making an epic comeback.
