This should (hopefully) get easier over time. From your dates there, it looks like the cards you have to re-learn often were only originally added 3 months ago? I think this should become easier for you in 6, 9, or 18 months – provided you continue to keep updated on the cards.

A. I definitely agree here. If I don't at least know understand a word to say, 30% confidence, I will never learn it, and will forever repeat it without making any progress. Personally I use images and sound to help make words stick in my mind. There's a lot of research about the effectiveness of imagery (see the "picture superiority effect.")

B. Ditto with #1. In scientific terms, this is called "encoding." Properly encoding things at the beginning has a big effect on your long term retention.

Also, as a side note, I have written a few blog posts on an old Substack about using Anki and AI tools:
