Great Question! Ray Redington has taken his mandatory 8 hour break while Pete and Richie have yet to take their 8 hour breaks. The average rest time for competitors at this stage in the race is a maximum of 4 hours. So when Richie and Pete take there 8 hour rest we can only assume Redington will take a 4 - a difference of 4 hours. Since Redington left 2 hours behind Kaiser and Diehl that would put him 2 hours ahead (8-4-2 = 2).
