I was a chicken for saying that "a 9:2x is definitely possible", and I proved myself right with an awful lot of wiggle room. I am ready to say this: "Not only is a sub-9 definitely possible, but also an 8:3x time, according to my sub-5-minute Plankton Pace I did earlier today". Speak of the devil, my best time on the level - in which I eventually did off-camera - is an 8:32.32, includes a late 4:59 Plankton Exit. Towards the end of the video, there will be my best times for every level that you need to pause to observe properly. (A few of which are now made obsolete)
