After using renshuu for several months, I recently started on "Beginner Kanji (N5)" and "Pre-Intermediate Kanji (N4)".
Subsequently, I noticed that my mastery levels for the corresponding Kanji terms in the schedules "Words for Japanese Basics" and "Words for Beginner Japanese" went back to Level 1. This, of course, reduced my overall mastery levels for the 2 aforementioned vocabulary schedules.
May I know the underlying reason for the reduction of mastery level, please?
There something in settings... yes, under vocabulary settings, there's a dropdown where you can select whether to drop vocabulary mastery levels to a certain level or to leave it the same, upon learning a kanji in the word.
This is probably because you're using kanji-related study vectors or the combined "Japanese" type vectors, like "Japanese->Meaning". That vector will dynamically quiz you on either Kana->Meaning or Kanji->Meaning, depending on whether you have learned the kanji in the term. You can check what vectors you study with and the explanation of these vectors by going to your schedule settings and clicking "Change these" in the "Currently studying" section.
Renshuu will not quiz you on kanji-related vectors for a word until you know at least one of the kanji in that word. So as you learn more kanji, more vocabulary words will have their kanji vectors "unlocked" for the first time, and since it is a previously-unstudied vector, the mastery level will be 0. The rest of your study data is untouched and you have not lost any progress, you're just having a new question type introduced.
Can you check your setting in "Vocabulary" setting?
"When I learn a new kanji" --> what is that set for you?
Mine is set to 'do nothing'.
@gillianfaith - Thanks for the detailed explanation. My initial hypothesis about the system behaviour was similar to what you have described in the second paragraph of your reply.
All in all, thank you to everyone for helping to answer my question!
