I meant that if I read a passage that has 600 words and mark it as read, it will count 600 words read. If I read 2x more during the week and mark it as read, now it should count 1200 towards the total amount of words read. Let us say that I have 5000k words read on my stats, now, after reading this passagem again 2x, I will have 6200 words read.
The minutes in Language Crush work like that, if I listen to a passage 10x, it will count the number of minutes x10 etc., so I would like to have the same with the words read.
There are studies that show that a certain amount of words read brings a certain amount of improvement to language learning and I want to test that.
