/jp/ - Otaku Culture

Greetings from /int/'s DJT.
You guys seem to be really into anki, which seems odd to me. I've been at it for about 19 months, and I only do 10 new words a day in anki at the most, often doing fewer or none. I feel like 90% of the new words I see (I do sentence mining) I either have a vague idea of what they mean thanks to my immersion, or can just easily infer mostly from the kanji + the rest of the sentence.
So what's even the point of wasting time with anki when a ton of immersion will get you better results?
