Two days per book full time means one every 16 hours. Enough to read the full Foundation Trilogy with one hour to rest between books.
On a side note, I'm ashamed to share that I tested my reading speed, and while it was 264 WPM, my reading comprehension was 50%. That's why I read slower, and frequently re-read.

Out of spite I tried to measure my Spanish reading, 520 WPM and 100% comprehension. Very unfair since it's my native language and I can glance and skip instead of reading every word.
This person could read for pleasure if they set the time for it. When I was coding all day, I didn't have the will to code for hobby at home, so maybe they had the time but not the drive.
Edited to add: hm. I just got 67%. I guess my college degree is a waste. Should have gone the humanities route instead.
I scored 100% at 500+ WPM for a couple non-fiction samples which felt like my usual reading speed if I’m not reading carefully. I read books at 200-300 WPM.
