I used to read ALL THE TIME, and I am quite sure that back then I read much faster than I do now.
I just went to an online test ( http://www.readingsoft.com ) and scored as 300 wpm, which they say is equal to 400 wpm, if the same test was done on paper. I will mention that I took my time, as there is also a comprehension test available to take after the speed test. At that rate of speed, I scored 100% on the comprehension part of it. I am confident I could have increased my speed by at least 50% and still gotten at least 75% on the comprehension part of the test. According to the article on the site, an average reader reads at about 200 wpm, and has approximately a 60% retention rate, while a "very efficient reader" can reach 1000 wpm, with a retention rate of 85%.
I have never taken a speed reading course, but was taught to love books from an early age - I can remember climbing up in my dad's lap to have him read articles from the Encyclopaedia Brittanica to me when I was about 3 or 4. You know that "little professor" thing they talk about? Yeah, that was me. It really, really pisses teachers off when a kid corrects them during class. AND is right. I did that several times before I figured out that it wasn't a good idea.
I still get told that I "talk like a book," meaning that I use grammatically correct sentences arranged in proper paragraphs. It drives me insane when I've only said two sentences about something, and the other person acts like I've been monologuing for hours. Waitaminute - you asked me what I think about Obama's health care initiative, and expect me to just say, "I like it," or "I don't like it?"
WTF! Trust me, I can show someone what a monologue is, but they better get something to drink, sit down, and get comfy, because two sentences ain't even a start!
Sorry to go off on a rant.
