That was interesting, but not very accurate imo. I know I read faster on screen than I do on paper. This test said I was reading 366 words a minute, but I know I am slower when its a "real" book.
The best thing about a kindle etc is being able to increase the font size, the bigger the font, the easier it is to read a paragraph at a glance.
Now see mine came pretty close. The speed is my general read for pleasure speed.
I can read Alice in Wonderland in an hour. I slowed down when I read Lucian and the Tattooed Tribe but I was reading differently. That's why I emailed you at 6 am my time to complain... [ahem.. you know the word I was going to use] that I had NO sleep that night. I started it at midnight and finished it at 5 am. but I reread parts also because I enjoyed them.
In general our speed varies depending on what task you are doing and why you are reading plus the content and style of the book. I read a book by Robert H. Eisenman about James the Brother of Christ very differently than I do about Jabin.
We do read at different speeds on electronic devices vs hard copy but we have different techniques for reading on both. Our eyes scan differently. Mine tracks pretty much the same but I had to teach myself to track and comprehend the same. Studies showed that we actually retain less if we are reading on an electronic device. We have to teach ourselves how to retrain and to track in a different way to do so.
What speed reading classes do is teach a method of reading that can be applied to both to speed up your reading. I put this up because some had asked about speed reading.
I will say I do read very different with most British writers. I have to read everything carefully. I have to slow down while reading them because the content is not just to set the scene, the content may play a very important part of the book. The mysteries drive me nuts. I can't read Reginald Hill the same way I read Robert Crais. I have to slow down for Hill.
