Immersion with japanese subs questions

I am just now starting to immerse. I just got my setup. I'm doing anime (The og pokemon anime) with japanese subs as my current plan. I'm wondering a few things

1. Is watching Japanese dubs with Japanese subs a good idea? I'm using language reactor on netflix and it's working great for what I want it to do.
2. When do I know it's time to ween off the Japanese subtitles?
3. I'm thinking of trying something. Maybe watch an episode once in English (or maybe english subs), again in Japanese with Japanese subs, and then finally without the subs. This is a lot of effort for a single episode, but yeah. Is this a good idea?

I'm currently N3 level and yeah. This is my first time immersing. I just recently completed my first manga volume in Japanese (it was also Pokemon)
