Welcome to the most unreasonable flick pattern in the game. It's about speed, but also about how you control your speed.
For hitting the patterns straight up, you want to go fast for the zig zag but also remember to slow down for the exit or you will break there. Luckily, you can just park at lane 1 and wait for the timing to slide the final 5 flicks.
If you're having registration problems, you want to ensure your finger is not skipping off the screen due to friction, which is unfortunately a very common problem with having to cover that much distance that quickly.
