Hi,
I noted that there is a difference between the correct percentage that i have doing a review session and the overall percentage after finishing it.
For example my last review session gave me a 91% during the session (until the last entry) and then the overall gave me a 75%…
The in-session percentage is calculated by dividing the number of correct responses by all responses.
The after-session percentage is calculated by dividing the number of correct items (whereby you got both the meaning and reading correct on the first try) by all items.
So, since kanji and vocab items have multiple elements, you can get 0% on an individual item for 1 wrong answer, but 67% on the corresponding 3 responses for said item.
But I suppose they could make it clearer in the display of the information what they’re calculating.
