From what I've heard, you need to prioritize immersing often and as long as possible each and every day. At first, you need to learn the basics including kanji and grammar, but after a certain point, you need to be immersing as much as physically possible. The sooner and more you do, the better. But from what I've seen from /djt/, it can take forever for something like this. You will need to start with easier to understand content. However, watching a stream after its completion in which you can rewind it and repeat the sentences, could allow you to get into Chammers content a bit earlier than outright understanding her live.
But take what I say with a grain of salt. I've just browsed /djt/ and read all of the guides a million times. I just never actually decided to take the plunge to learn.
