Hi,
let’s first imagine (actually it’s not necessary since we’re talking present reality) that you have three bundle reviews coming up today. One is for ten kanjis at 11am, followed by fifteen vocabulary items at 2pm, finally finishing the day with 12 other kanjis at 4pm.
However, you have time to study today only when it’s 7pm. So, suddenly you have 37 items from three different sessions to sort out instead of just the ten kanji characters.
Nowadays (the present reality), these three bundles are literally bundled together i.e. they are mixed into one big review session. In my opinion, it would be a better studying experience if the first bundle from 11am were questioned as a whole first, and only after that the second one from 2pm would be activated regardless of the fact that they are both due to a review at 7pm.
In terms of 居酒屋 dinner, it would be a similar setting to the 味噌汁 being served first, followed by the main course after the soup is finished, and the dessert last, with all three meals in respective order although they are a part of the same dinner.
Currently WaniKani hopefuls have only partial control over what to study and when. Why not expand it further?
best,
Jari
