As a brief commentary, below is a review of some of the splits with the biggest time loss (as compared to best).

Waltz: 1 min 25 sec (lost): A very unfortunate run through Mt. Rock, including three ambushes.

Trick or Treat: 1 min 12 sec: The fight was good, most of the time loss was from the swamp.

Herculean Boar: 1 min 07 sec: There was a ~20 second encounter on the way to the boss. The fight itself was slow.

Hidden One: 1 min 04 sec: A very slow boss fight. Missed the first and seconds Shadow Silhouettes with Salsa due to bad positioning and the tricky hit-box.

The End (Game Clear): 54 sec: Ideally you don't need a second combo from Falsetto and things go something like this: the boss moves forward for his first turn instead of only using ranged attacks; you set up Shadow Silhouette + Hawk Eye; Viola runs to the north-west, fires off one round of arrows for ~400k while you're building echoes; Falsetto gets off her combo; Viola fires a few more arrows for ~100k, and that's enough.

Since this run I've made a few small changes.

Root lurker now done with March, Full Moon into Supernova, rather than Viola arrows. It's very fast and more consistent.

Picking up Alice's Watch now. Lets you fire more arrows. Doesn't look like it should, but it does.

May post some updated notes soon, here in the guides section. Hope to see some other PS3 runs posted. Would be cool.
