yeah i thought you messed up at the beginning or it would have beeen at least 2 seconds faster but still you can see your trick dosent gie constant speed like the original path does.
In my humble opinion, i guess with bones fast start until the 5th flag, and with Kris fast ending (really speeding here ), 55 could be reach but not more than that
Remember PMD, you need someone to slap you if you think to play this level again
