I’m currently playing around a bit with the Wanikani-API and I can already import all the data into an Access-Database. Yeah!
Now I want to do some analysis stuff with the data and found something in the data that doesn’t make sense to me. I hope someone knows the answer and can explain it to me:
For each review item in the collection I read the data_updated_at and the created_at dates and write them in my db table. Now I noticed that for about 10% of all the review records the data_updated_at is bigger than created_at. Sometime even around 30 days.
Now my question is: What’s the reason that a review record is getting updated? And why sometimes 4 weeks after the review has been created?
Thanks for your help!
