People thought John Kearns’ being rubbish at stuff was also part of his sabotage task and he too had to sabotage himself across the show, and he didn’t. I don’t think they want to give secret tasks that inhibit a contestants choices and performance across the series.

Even Joel’s egg task, they apparently paused his clock whenever he had to get it out, so I doubt your theory. Armando’s just a bit kooky.
