I want to attempt a guess at when the first finishing team did so and when the 8th team did so. Here's my timeline:
6am ticket Office Opens
7am Train leaves Ouagadougou station (pure guess)
8am arrival at Bingo (assumes train moving at 30 miles per hour)
830am First team completes Camel milking
915am Last team completes Camel milking
900am First team completes Teach/Learn
945am Last team completes Teach/Learn
915am First team at Pitstop
1000am 8th team at Pitstop
the implications of this are on the completion of the next pitstop. Teams have to be at Ouagadougou airport before 11pm on the next evening(July 15) if they are able to catch the Air France flight to Paris. With a 12 hours pitstop, they have a maximum of 2 hours to get to tasks, do tasks and get back to the airport. My conclusion is that it isn't going to happen and World Race Productions, anticipating that, schedules a 24 hour pitstop and they fly back to Paris the evening of July 16.
Anybody's thoughts on the above timeline are welcome.
