Just a reminder that the teams don't necessarily know if the detour task choices are in balance; they just want the one that is easier and faster for that team to finish. There's no guarantee they will be balanced or not, or fast vs. slow, and most teams are in such a rush these days they often don't think it through, especially if they're provided a supplemental sheet that they can review, but often don't, before choosing.
To me, from a Race perspective, this was a tough and interesting leg. The leg design used cultural elements and locales in their design, and some teams did not pay attention to details. Some teams took advantage of tasks and their skill Sears to improve their placements, Brodie Kurt, Sheri Cole, even with an unforced error and a penalty. Methinks that placement of a double U Turn in this leg was wasted, it was too early and would have been better in another couple of legs.
The biggest shift in placement, and time, goes th Sheri-Cole, especially Cole, who managed to make up time to the pack at the top. The penalty did not help, but it may not matter if all the teams are in a pack together when they leave Columbia.
