StepMania - Fly Like You ESP 999,580 PFC [DDR GP] 

I spent 2 hours straight going for a score until I was satisfied and I can say this is my proudest PFC score in StepMania. I've technically PFCed a 16, or AAA 17s but nothing comes close to the grind on this song, which is why I decided to upload this.
I most likely won't be uploading any more StepMania videos so enjoy this one-off video.
Fly Like You by technoplanet is a song from DDR Grand Prix, but since it doesn't exist in the arcade version of the game, I downloaded it to stepmania to play.
The marvelous window on this song feels extremely hard, most likely due to the high BPM of 286. The play here destroyed my previous bests as seen at the start of the video. My heart was pounding at the end so I was super satisfied to get it.
I use custom Timing Windows for StepMania, which replicate DDR exactly:
Marvelous: 1 frame on 60 FPS (16.67 ms)
Perfect: 2 frames on 60 FPS (33.33 ms)
Great: 91.67 ms
Good: 141.67 ms
This means every marvelous is hit within a 0.016 second window.
Played on Keyboard, numpad keys. 4 is left, 8 is up, 6 is right, 2 is down. Index fingers on both hands (emulate DDR pad).
