During the creation of this I found more beneficial use of 0ms object boosting. Normally you need to be able to push the pushable in the direction of your desired boost. With 0ms however the pushable doesn’t have time nor need to move at all, making it possible to boost in any direction even with pushables that is either shoved against a wall or placed stuck outside the world by the developer.
The boosts at 3:14 and 6:05 could both be implemented in the same run, but I discovered too late and didn't bother to redo.

This is an experimental showcase route for entertainment purpose that is not likely to be any faster than getting grenades in Office Complex unless new strategies are found.
With the grenades you could:
- gib headcrabs in OC vent. Saves only about 1,2s since you got to cook the grenade from map start
- killing crab and box before first stair could save up to 0,5s
- a 20dmg boost could save 0,3s in the hallway before barney
- potentially use OC barney in a faster manner

Collecting the early grenades took 5,336s extra so it all depends on how fast OC barney can be made with the grenades already acquired.
Getting the grenades at barney took about 4s in HL21, but that can obviously be improved a lot in a TAS.

The footage is captured live from the hltas execution with a under development build of bxt-rs. A big thanks to YaLTeR for the tools and support.
The slow motion is captured at 500 fps played back at 60 fps. A rather slow x0,12 rate to be able to see the object maneuvering.
