The Godlewski family is in third place as a result of a poorer first half of the leg (i.e. prior to the campsite), while the Aiello family makes it into fourth place due to their good showing in the first half of the leg (they were the first team to arrive at the campsite).
The Rogers family is down in eighth place because they lagged behind the other teams for most of the race, but performed well enough at the Detour to give them a fourth place finish. The Linz family did well enough in stages (first to the sports store, and fourth to arrive at the Detour) to result in them being ranked ahead of the Rogers family.
Need I explain why the Paolo family is ranked in tenth place?
