It's a pity that most people don't see the actual cause of Jenifer's poor performance.
The organizers of the show are the actual defaulters here. I watch CBS Survivor series, a programme where GUS lifts almost all its tasks/challenges from, and in this show, they pay great attention to details to ensure equality amongst all contestants during their task/challenge (considering height and weight differences between contestants). This attention to detail is one thing Gulder Ultimate search lacks.

In my opinion, all contestants are not of the same height. GUS missed the detail by making the obstacles the same height irrespective of height differences. Jenifer is obviously the shortest contestant and you can see she had more difficulty navigating the box obstacle and at some point, her feet kept getting stuck. you could say she was literally jumping in/out of the box, so how do you expect her to balance her ball on the slab?

Correct me if I am wrong but I feel GUS should pay more attention to details.
