muahahah I saw WK people using it on Memrise (surprisingly one of the most popular decks there it seems), so I just went for it 
Thank you ^^
Yeeep, Iβm a big fan of separating siblings. It makes things stick so much better, and itβs not that much more effort. You get more reviews, but since youβre only doing 1 sibling you can really go through 100 reviews without getting tired (at least from my experience). I usually have them separated by 23h so that I can see the layouts in consecutive days 
I used it for the katakana vocab deck and I also recommend it for Core 10k, mainly if you want to also study EN -> JP ^^
The only thing that I wish would be a way to choose which siblings get separated or not. For example, it makes sense to separate EN -> JP, but itβs fine doing JP -> Meaning and JP -> Reading together. The problem with separating the 3 layouts is that if you have a 23h interval between siblings, it will take 12 days to get an item out of apprentice. Itβs too much. Not only that, but doing a lesson, waiting 4h and then waiting 23h right after is just asking to get lessons wrong. Itβs too big of a jump, at least for me.
Iβve mentioned this to Neic and it seems to be something hard to build. Another solution was being able to choose the intervals between siblings just like you can choose the SRS intervals. That seemed like a good solution, as it will fix the 4h to 23h jump, since 23h is the interval I usually recommend ^^
It didnβt take much tbh since the deck was built on other platforms already but thank you ^^
Next is a Russian deck
