I found some speed reading tests online and did this one. I chose it since it had a normal text to read and it also measured the comprehension afterwards. According to the test I read real slow, 157 wpm, but the reading comprehension was good, 91 %. 157 x 0.91 gives an ewpm of 142 which is average.
It is really amazing if it´s true what the text said, that an average reader is compared to a pianist playing every day of the week for 20 years and only able to play music like a beginner, or a racing driver never exceeding 30 mph. Since we do most of our learning by reading we should learn first and foremost speed reading in school. This should be a subject as well as studying techniques.
