Reading time. The book describes this plan as averaging about 12 minutes a day.
Measuring the real word count of every day's reading (via the same passage source this site uses) at a
typical 200-words-per-minute silent-reading pace, the actual daily average comes out to roughly
10 minutes — close to the book's figure, and consistent with it if read at a slightly more
deliberate, reflective pace (around 170 wpm) rather than brisk silent reading. Individual days vary widely,
from under a minute to nearly 24 minutes, depending on the chapters assigned.
