Best ratio of known-unknown words

This topic has been initiated before, but I want to hear the expert opinion of fresh masters of the community.

I’m not a master just opinionated.

My own reckoning is that 25% unknown words and below is the sweet spot for me.

If I want to rip through it, it should be less than 10% unknown words.

At about 35-40% unknown words it’s essentially unintelligible to me.


Cool! I want to do more extensive reading, since it is, according to my research, one of the best things you can do to improve in a language.
