So here is the "long and the short" of my hypothesizing about leg 6:
1. No matter what else, James and Sarah will start at least 4 hours behind Shane and Andrew, who are behind 4 other teams.
2. Ross/Tarryn start at least 4 hours behind Shane and Andrew and also have a Marked for Elimination penalty of 30 minutes if they fail to place first in leg 6, which would be virtually impossible unless there is a major bunching point, unlikely since they are not traveling elsewhere except maybe on buses to Gallipoli.
