I recently took intrest in speedrunning party games, and while taking a look at the current world record for 1st place Solo (6:17 by Hazry) I noticed throughout the video he never proves that he is not in a party. I am confused as to why this got accepted, and would like to clear some doubts.

Also I find suspiscious how in the run, during the fire leapers minigame, the highest score was five (usually goes on for much, MUCH longer) and then proceeded to have other two people complete almost flawlessly Chicken Rings and Jungle Jump
