I finished volume 5 yesterday. Story-wise, google sensei tells me I have just finished the first season of the anime plus some OAV apparently, if that tells you anything.
That’s hard to measure, but around 99% comprehension? (~1 unknown word every 100 words). I usually go by unknown words per page, but since some pages are basically covered in screams in this book, it’s a bit less reliable.
But it also helps you get better! As time goes on, it will get easier and easier.
I second that recommendation! I learned ~3k words with Floflo, specially tailored to my needs (by virtue of being the words that I often come across) and it really helped bring my reading to the next level.
It can be tedious at first, though, so don’t just add everything in there, just words with high enough frequency. If a words is going to show up 10 times+ in the book you are reading, it makes sense to learn it. If it shows up only twice? Eh, two dictionary look ups aren’t that bad.
Just saw you are already doing FloFlo. I should probably read everything before replying eh?
