Same here, old brain, have restarted a few times already.
I changed my strategy around level 10.
Daily lesson includes 8 kanjis and 16 vocabs — if available. I set the batch size to 8 in the app. I do use the Reorder Omega user script so I can do my 16 vocabs even when kanjis are still available.
It takes a bit longer than doing all lessons as they appear, but the workload becomes very regular. Here is what it looks like:
- Left half: lessons as they appear.
- Right half 8 kanjis / 16 vocabs / day
Level duration has been around 8 days since level 3, with all levels between 7d and 9d. These are still somewhat « easy » levels, though. I’m not sure I can keep this pace for the Hell levels…
