Another 0% attack

Or maybe it's the same if you didn't deploy since 2016.

ff dd f dd f dd f d ff ddd f dd f dd f d f

and if you are lazy as I am:
sleep 4s; xdotool type 'ff dd f dd f dd f d ff ddd f dd f dd f d f' and focus your browser in 4 seconds afterwards.

As prediction is based on first five letters inputted, any first five letters can lead to a 0% score with enough repeats. Your sequence displays 0% but the computer still predicts you sometimes.
Taking your first 5 inputs and turning it into the sequence:
ff dd f dddddd f dd f d f ddd f d ff dd
will lead to the computer guessing wrong EVERY time, simply due to using its own determinism against itself.
It's admittedly satisfying to look at it going wrong!
