掲示板 Forums - Schedule chaos after a small change

I just activated a Renshuu pro bonus from your summer offer (thanks!). I immediately went to try the listening questions (sound>meaning) on my N3+N2 schedule, and to keep the schedule down to 3 vectors, I removed the kana>meaning vector, which is pretty much its mute equivalent.
But things didn't go as expected: immediately, I was 3000 words late on this schedule, and most words dropped to mastery level 2. I did a few questions anyway, and I agree, it's better this way... But the overall mastery level dropped to 33% when it was 67% a few minutes earlier.
I went back to kana>sound, but I'm still at 33% overall mastery for this schedule, and still with a crushingly enormous schedule ahead to complete.
Would it be possible to undo this and get back to a manageable schedule, please?
Would it be possible to introduce words to the sound>meaning vector by assuming the mastery at this level is the same as the kana>meaning mastery?
Most likely, our memory will be triggered slightly better by the sound or by the writing (I'm betting on the sound), and mastery levels will end up being different for those 2 vectors, but for the sake of not getting an additional 15,000 not-so-useful questions, it would be great if each new word introduced to this vector starts with the same mastery as kana>meaning. It would also be another measure to prevent schedules to run out of control. In my case, 15000 questions is 4 months of vocab questions, meaning my vocab level wouldn't actually improve for 4 montgs, with no new words, instead of ~400 planned.
If you can do this, I would guess the reverse measure would also make sense, for someone who usually does sound>meaning questions but cannot make noise in some occasions.
I'm looking forward to try the vocab in context questions, but I'll avoid vocab questions for the moment and check out the grammar questions.

PS: as a favor to you, I could manually adjust all your listening vectors. If so, tell me once more which vector or vectors you'd like to use as a base for generating the new levels.

Should be good! (or, if you are reading this the second I type it, it'll be good within a few seconds).

On the summary page, if you click the title above all the mastery levels and toggle off of Overall and onto the other vectors, you can see that it is kana->def that is pulling everything down. You said that was in the schedule previously, right? Study vectors cannot affect the vectors of other ones - simple mode just moves them all up one on a correct answer - it does not move them all up to the same one.

Any ideas as to why about 1700 terms are still at L3 for that particular vector?
