TIMESAVE: By starting to input a frame late, you get a different word, that requires less movements to clear, thus, being faster!
TIMINGS:
Power on - Select press: 386 frames (6.4629s)
Power on - End screen: 426 frames (7.1324s)
First input - Select press: 30 frames (0.5023s)
First input - End screen: 70 frames (1.172s)

1 frame of delay - ANGER - 30 frames (386 frames from power on) - The fastest so far
2 frames of delay - FAULT - 50 frames (407 frames from power on)
3 frames of delay - PLANE - 34 frames (392 frames from power on)
4 frames of delay - STATE - 46 frames (405 frames from power on)
