At what point should I start listening to Japanese podcasts?

I ask this because I’d had planned to start listening to Slow Japanese by Mochifika and Thinking Out Loud by Mel after understanding some basics of the language.

But I still don’t understand most of what’s being said.

I see a lot of posts recommending these podcasts for absolute beginners – but also I’ve seen advice that comprehensible input of 80%+ is best to learn. I’m struggling to understand even 5-10% of these podcasts so is it still too early?

I understand I’ve only been learning Japanese for a couple of weeks through Genki and Anki.

Should I be finishing Genki 1 before starting to listen to these beginner podcasts?
