StarTalk
Its videos run from 40 to 91 on a 0–100 scale, with a median of 70. That is a spread of 51 points — wide enough that a single level label would be false for the channel's own hardest videos. 108 of its 108 scored videos pass 40. 31% carry human-written subtitles rather than auto-generated ones.

Each bar counts this channel’s videos in one ten-point slice of the scale. A median alone hides that shape, which is why the ranking shows a range rather than a single level. Bars from 40 up are dimmed because the advanced shelf begins at 43 — that is the part of the channel that stops being an easy watch.
