Now the goal is to find the values of desired retention that minimizes the workload/acquired knowledge ratio. For more details, please read this: https://github.com/open-spaced-repetition/fsrs4anki/wiki/The-Optimal-Retention. It's important to note that you can set your desired retention higher than recommended if you want to do **more** work (minutes of studying per day) to remember **more**, but you shouldn't set your desired retention lower than recommended because you would have to do **more** work to remember **less**.
