After reading how it works, I can get to around 50% by doing the following: pick a pattern of f's and d's of length between 1-5. Type that pattern. Pause for a second or two. Then change the pattern. Patterns can be, for example: only d's four times; alternate between f and d three times; single f; one f for every two d's two times. In fact, now that I "get it", I don't even need to consciously pick a specific pattern, I just smash the buttons and "somehow" change the way I smash them every five or so smashes. I get around 50% prediction rate pretty consistently with this.
