My guide for VR recording and LiveSplit hotkeys is linked below. It was written for Scanner Sombre, but works here too with the following notes:

• There is no bounds size restriction for this game in the rules. (The game enforces one on its own.)
• Starting the game happens with a hand motion instead of a button click, so you have to start the timer and sync the hand motion yourself. I find this easiest with the split hotkey combo on my left controller and the motion with my right hand.

These are the hotkeys I'm using:

• Left menu button (ctrl), left trigger (num1): Split
• Left menu button (ctrl), right grip (num2): Undo Split
• Right menu button (alt), left grip (num3): Reset
