How much time to spend on Anki every day?

Hi, I am a final year medical student from India. I started using anki from New year of 2026.

In these past 8 months, my daily load has increased to 450 cards now. This takes roughly atleast 90 minutes of my time every day just to finish the due reviews.

When I add more new cards after studying new topics, this is expected to increase even more.

So, I wanted to ask you all. Am I overdoing Anki? Because on many days, I am not able to study any new topic. The whole day gets spent just on doing the due reviews.

What should be ideal team to spend on due reviews per day or the daily card load?
