My best interpretation of the test results is that Bionic Reading is just an exotic text styling that has no impact -- positive or negative -- on reading speed or reading comprehension. If it were a form of speed reading, we would have observed faster speeds when using Bionic Reading (and probably lower comprehension as a trade-off). This is NOT what we observed.
