To add to Leg 1 speculation - you can infer that the difference is at least not significant enough that the team eliminated is from the first flight, which is good and definitely makes the otherwise imbalanced 7-4 team split feel fairer.
Also, if you checked footage of the first Roadblock from the team bios, and assume that the Roadblock is the task before the Pit Stop (I think it is - Leo & Alana are seen running off a beach area with a clue in their swimsuits when they did the goat racing in swimsuits as well), then we can have a potential fully spoiled placement slate.... going off promos alone and team bio footage, which is kind of funny to me.
My spec: (all built off like 3 seconds of flashing footage each and checking the background)
1st-4th: Any combination of Will & James/Riley & Maddison (seen together at the RB), Hung & Chee (only seen alone), and Victoria & Michelle (only seen alone)
5th: Eswar & Aparna (you can see them celebrating while seeing the other teams in the background, none of the first four)
6th-8th: Any combo of DeAngelo & Gary/Leo & Alana/Haley & Kaylynn
9th: Lavonne & Kellie (there's shots of them looking worried with only Cody & Nathan/Jerry & Frank seen)
10th: Jerry & Frank
Last: Cody & Nathan (Jerry & Frank are shown reading a Route Info clue post-RB and you can see a camera crew still filming a team behind them)
Should be an interesting premiere to watch. I'd be surprised if our Top 3 was also the Top 3 for Leg 1. Would be the third TARUS season in a row where that happened... and both the 2nd placers on Leg 1 (Cody & Jessica/Colin & Christie) ended up winning the Race, with the Leg 1 winners eventually finishing in 3rd and the 3rd placer on Leg 1 finishing 2nd.
