I’m on level 11 in wanikani and I wouldn’t do it unless you have a lot of free time and also don’t want to actually see if you can recall the reading/definition in the set times. I started out doing both, but I found it more effective to go to Japanese sites/pod casts and actually see how they use the vocab. This is normally with items I doubt WK would teach such as law terms and phrases. There are a lot of subtle differences in the various vocab phrases that roughly translate to the same meaning in English. I feel that WK and rtk don’t really go into that, but the later levels might.
I also starting missing the answers a lot more once I stopped using the anki deck since I wasn’t testing them so often.
