Yeah, that's true. And we don't even know if they were in photofocus while photoreading the book. Because if they weren't, then no wonder it didn't work. And as I see from the forums most people who don't have photoreading working have problems with photofocus.
And secondly, people who have studied engineering and physics (as I have, I'm an electrical engineer) must know the good old wisdom about experiments: "One experiment is not an experiment."
What makes NASA think,whose applicants are also engineers and physicists (mostly), and believe themselves to be absolutely perfect in physics, that it is not true for photoreading?
And for the other hand, you all know: "Practice makes perfect."
Why would be photoreading the exception from this?
