I only just started using WaniKani and thought I understood the review sytem after reading about it in the FAQ and forums. But now that I got to level 3 I noticed the wait time from apprentice 4 to guru for the radicals is significantly longer than 24 hours while in the first levels I believe this was 22 hours.
For reference I could do both radicals and kanji from lesson to guru in around 4 days for the first two levels while I still need 24 more hours to unlock kanji for level 3 while still doing reviews a few times a day.
So may question is basicly the title: ‘does the review change between levels?’
