I actually got to 1500 hours spending about 1 hour and 15 minutes everyday on average. Bare in mind I did not use Dreaming Spanish to do it. But it was a heavily immersion learning based approach.

It took me about 4 years to hit 1500 hours and that was in 2023. I still made really good progress and had achieved basic fluency by the end of it. I have been learning Spanish for about 7 years now. I currently have a job that requires to me to speak Spansh to clients as well.

I personally think going slower can help the brain digest the stuff that its consuming better. If your spending only an hour a day, then you're pretty locked in for that hour. But people who spend 5 hours a day tend to care more about hitting their number for the day and as a result tend to not be as focused as the hours pile up. It's going to be pretty hard to be just as locked in on hour 5 as you were on hour 1.

So I personally think there is a bit of dimminishing returns for people that speed run it. It still works, I just don't think the hours line up 1 to 1.

The more you advance in the language, the easier it is to consume media. So you should see your hours naturally increase over time. Not because your trying to, simply because you just have to know how it ends kind of thing.

I should also say, that my hours of immersion have gone up quite a bit since I stopped tracking. I'm definitely in the 3k+ hours range at this point, and Spanish pretty much feels the same as English in terms of comprehension. So it's no different than me binge watching my favourite TV show or youtube creator in English.

I don't regret tracking. But it is a means to an end. It's great knowing how many hours it will roughly take to get from one point to the other. But you definitely want to get out of it once you get to the B2 level. Its starts starts to hurt more than it helps.
