Here are some other thoughts:
TAR 10 - If BQ did not get lost in Morocco, they would finish 1st in that leg leaving Rob/Kim NEL. Though R/K got 1st in Barcelona now, I am not sure if they would still choose the same detour if they were marked for elimination. They may act like BQ and choose the physical detour as well. In this case Lyn/Karlyn would get 1st and R/K eliminated. Then Tyler/James and BQ would fight for the million dollars (L/K cannot run as fast as them) in New York but T/J still got the advantage.
TAR 16 - If Brent/Caite did not u-turn Carol/Brandy, C/B would probably u-turn the cowboys making them eliminated in Singapore. And I am sure Michael/Louie would be eliminated in Shanghai anyway since they were not good racers at all. So Dan/Jordan, Brent/Caite and Carol/Brandy would make the final and judging from the tasks in finale I think anyone could win it.
I think if the Singapore u-turn is a w-turn, the result would be like this!!
TAR 19 - Even Jeremy/Sandy did not lose that much time finding the Dump, I still think Ernie/Cindy would win the Race. That may be a closer race but since Cindy is clever enough to call Atlanta Tourism Board for directions, that means they would not waste a minute in finding the Dump and would catch up with J/S. I have to say calling tourism board is really a brilliant idea and it contributed A LOT to their win, even Andy/Tommy made the final they would not be able to beat E/C because of this reason. So now I hope the producers would ban future racers to do the same which made the race more exciting!
btw, whom did Nat/Kat call in TAR 17 finale to find the studio? Is it also the tourism board?
TAR 18 - What if Kent/Vyxsin did not incur penalty in Switzerland? Would they make the final or win?
I think they would beat the Globetrotters in Brazil provided that they also made the 1st train, and so they would make F3 and I am sure their edit would be completely different this way!
