I think to get accurate total results, you have to add the total laps from each day. #2 could have finished 2nd (or even lower) on both days, as long as the person in front of them wasn't the same car both days, their total laps would be higher. More laps = the win.
James, I think #25's driver changes don't show up on the lap chart because they got so far ahead of everyone else. Look at the first few laps. He was gaining 8-10 positions or more per lap! By the time the first driver was done, they were far enough ahead that even with their driver change, they were still laps ahead of the next car... thus they were still #1 at the top of the list.
Cool, eh? It's a shame about that whole People's Curse thing.
