"Random" Randomizer

Someone has questioned this since Season 1 but sometimes it seems like a producer picks the spot when the randomizer is going. Season 1 I remember hardly anyone in the bottom left got picked until like the 4th episode.

It seemed way too convenient for it to go to the spot where only the guy who was the whale could be challenged. He's now won 4 times in a row and it was the last duel of the night so it makes sense to try and make it interesting and knock him off. If anyone suspected the randomizer isn't random, this would've been the perfect example to prove that.
