Yes. That’s absolutely possible. In fact, I believe you can go to about 1000 wpm and keep an amazing comprehension level, but that of course is going to take months.
Here’s my story (hopefully you’ll get something from this).
Speed-reading piqued my interest about 3 months ago. I’d watch all types of youtube videos, and read dozens of books about the topic.
After some time (within a couple of weeks), my wpm went up to about 600 wpm for a normal novel-type book. If the book was a heavy textbook required for my college, I’d read at about 400 wpm.
My wpm didn’t go up for a long time. It was stuck in the 600-wpm range for a couple of weeks. After studying, I realized my problem.
My subvocalization still existed. I know you’ll never be able to get rid of the damn thing, but I found a way to use it to my advantage.
Since you’re on this forum, I’m pretty sure you’ve heard about the mind palace. That’s what I use when reading.
When reading text, I memorize the entire book, not word for word, but for event by event. I transform the book into a movie and memorize that.
For example, when I read/hear: he ran to the store, I actually visualize a man running to the store. Because when we read the text, we go through 4 phases.
- Actually reading the text.
- Understand each word individually.
- Understand the final sentence.
- Understand the sentence with the context of the book.
But when you visualize the words, here’s what happens.
- Actually read the words.
- Visualize the words.
My memory isn’t perfect. I do forget a ton of stuff, but for the majority, I do remember most of everything.
The mind palace I use is the setting for each book. For example, I’m currently reading the entire Sherlock Holmes collection and the mind palace I’m using for those books is 221b baker street, his flat (British for an apartment), or his lab, whatever.
Unfortunately, there aren’t any good books or youtube videos out there that talk about this method, so it’s really just a try-fail method.
Anyway, best of luck to you!
