Skitter.
It's that easy.
Rather than pushing your brain not to subvocalize while moving your eyes about the same way, allow your brain to find a new way to move your eyes.
Now, you're going to run into the Keyboarding Paradox. That paradox is, if you go from hunt-n-peck to a systematic keyboarding technique, you're going to reduce your typing speed. Skittering will probably slow down your reading speed. (There is a chart in the Photoreading manual showing skittering as being about 100 wpm slower than superreading).
As your brain compensates for the inability to make sense of subvocalized skittering, you will increase speed.
