I Waited, but This Spring Never Came out of That Pipe - Uncleared Levels, Mario Maker 2

How many randomly picked uncleared levels can I clear in a row? I get 20 minutes, no skipping, and no level viewer to keep the streak going. The timer in the bottom right counted down in real time as I played the levels. In Mario Maker 2, all levels must be beaten by the creator of the level before they can be uploaded. Apart from this initial "clear-check," none of the levels in this video had been beaten by anyone before I came across them. The levels were picked randomly from a set of older uncleared levels. No third-party tools (e.g. level viewer) were used to assist in the beating of these levels while the timer was running. This video was edited by ChrisWasCrossed.
