Why 1x is the median of the ten nearest uploads, not the lifetime average
Every multiple in VideoCore and Lens compares a video with the median of that channel's ten nearest uploads of the same kind, five before and five after. Here is why that, and not an average.
What 5.8x means
This video has 5.8 times the views of a typical upload for this channel. Rank 1 of 25 comparable uploads.
The definition is printed
At the foot of the panel: outlier equals views divided by the median of its ten nearest long-form uploads, five before and five after. 1x is a typical video for its time.
Why the median, not the average
One viral video would lift an average and make every normal upload look like a failure. The median ignores it, so 0.3x and 5.8x on the same row both mean what they say.
Why nearest in time, not lifetime
A channel of 560 videos has grown. A 2015 upload is not the bar for 2026. The ten nearest uploads are the channel as it is now.
Why it works this way
A multiple is only honest when the bar is the channel at the same moment; nearest-in-time medians are that bar, and a lifetime average is not.
