Regarding people's rate of speech, I see that several comments mention watching at higher playback speeds, as do I. Depending on the accent, material being covered, and presentation style, it's possible to save a lot of time this way.
It's odd that YouTube provides 1.25x, 1.5x, and 2x playback speed settings, but only one rate, 0.5x, that's slower than normal. Isn't that a bit too slow? If you're listening to someone who speaks very quickly (as some others have lamented earlier), a speed of 0.9x or 0.75x would probably be more helpful. No?
To those who've commented about people speaking too quickly, do you change the playback to 0.5x or is that too slow?
Only youtuber I could imagine watching at 0.5x speed would be Collinfurze
