two types of flow. One is called absorbed flow and the other is
    called panoramic flow. Absorbed flow is when you're doing a task,
    like, minute tasks like taking apart a watch or something. And
    you're so focused that you enter the world, and then you look up
    and time has flown. All of a sudden, how did an hour go by?
    Martial arts has a little of both, but in some ways, to do it, you
    actually have to go into panoramic flow. You have to let go of
    your mind. You have to trust that the training, the implicit
    memories available of the actions, and the physical actions, and
    then you have to trust that there's this way of organizing
    information that's faster than thought. And by doing that, you
    enter into a flow. And that's being done from this awake
    consciousness. That's the functional feeling of that. And there in
    itself, just like Csikszentmihalyi, who wrote the book on flow,
    and gives these qualities of flow as that activity is in itself a
    pleasure, that there's a loss of a sense of ego or self, sense of
    timelessness, sense of connection to everything. And so that
    state, you're doing that activity to find something that I'm
    saying you can find anytime you want. […] Who, what level of mind
    is it that can do martial arts at that level? That you that does
    that, that's the awake consciousness.

It’s when we train our subconscious mind to simulate reality so well that it accurately stays ahead of what’s happening in real time.

A smaller example of this is reactively catching something that was knocked off a table and realising what you are doing in the moment without having triggering the reaction consciously.

being unable to execute this during a match like a duel means being at a massive disadvantage.

Compared to an RTS, yes. Compared to tactical shooters like CS, no. Once you reach a certain level of aim, movement and the associated mechanics become the main distinguishing factor along with using the sounds in the game to track your opponents position and conceal yours.

Hah, that description kind of reminds me of Gunz, where some bugs in the game lead to players being able to climb walls, basically fly around and attack rapidly while moving.

Here's a timestamp in a video that talks about it: https://youtu.be/zvC67kmYxPA?t=82

Though it was a third person game. Imagine creating an entire way of playing a game because of bugs in your code, though.

I see it's still a thing in CS:GO: https://www.youtube.com/watch?v=hMsPf8eSW3k

And I'm 95% confident that surf maps were one of the inspirations behind Titanfall. Here's a completely broken tool-assisted speedrun of the obstacle course: https://www.youtube.com/watch?v=yXtggqe6oo0

Maybe this is somewhat related to the subject of the post: detach consciousness from what I am doing and the pain gets a little detached too. However I doubt it would work with serious levels of pain.

The traditional approch is pain killers and some meditation.

VR helps a lot.

On two front : it distract your brain and it can teach you how to reach that distracted from the pain state by yourself.

My understanding is that a large pourcentage of the neurons are specialized in image processing. And that keeping those busy with exploring a VR world avoid to have those neurons re-assign to ponder about pain.
