Can I please get some clarity on how the most commonly used words are chosen at Lingq (Mandarin Chinese)? So I understand the 4-coin words are the most common, but I'm interested to know whether they're the most common 500, 1000, 2000 etc? Likewise with the 3-coin and 2-coin words.

Also how were the most common words ranked? Like was it through that SUBTLEX-CH TV and Movie subtitle list? This seems to be the most useful ranking as it's probably as close as possible to the word frequency of spoken Chinese, rather than written Chinese. I ask this because I'm tagging all my 4-coin words that come up and prioritising revising them but lots of them seem to be more commonly written than spoken/more formal. In other words they seem to be outside at least the most common 1000 spoken words (like 将 which seems to be a more formal 会 and 如何 which seems to be a more written/formal way of expressing 'how'). I understand this is a bit pointless to be pedantic about because I'll hopefully be learning them all in upcoming months anyway but I'm interested.
