I've tested myself several times and found I can usually read 1.5 to 3 pages per minute for a typical-size paperback, depending mostly on how "in the zone" I am (with a minor effect from complexity, but most published novels don't different much in reading level). Even down at 1 page per minute, there are plenty of 200-page books so 1 is a reasonable lower bound. Except, the article spreading it out to only 8 minutes per day means you'll never be reading long enough to get in the zone, so ... One notable observation: you need to aggressively prune away the possibility of reading anything with bad (or even inconsistent) grammar; exposure to it poisons your brain's ability to read and write correctly.
