I did around 4 hours of active immersion today but Im wondering if Anki will really play that large of a role in the language learning process. I remember seeing something saying a ratio of 90 minutes of immersion and 30 minutes of anki but is more than 30 minutes even that helpful? Its a supplement but would it help if I did more that much? Obv you have to watchout for burnout but should I even bother doing more or just focus on more immersion at that point?
