Yes, I started around the same time as you, with very similar feelings and motivations!
I came across a very useful tip right here in the forums and I’m thankful for it every day since then:
The idea is to do your lessons first thing in the morning. Say between 7 and 8 am. That way your first review will come at 11am and the second review at 7pm. Stick to these times and your whole WaniKani experience will become very consistent and predictable.
So this leaves me with a typical day of 30-45 mins first thing in the morning, 5-15 minutes at 11am, 5 to 15 mins at 7pm and around 45 minutes last thing at night (around 10:30pm)
I am on this pace by taking 5 Kanji lessons or 15 Vocab lessons per day. When I’m doing Kanji Lessons I take a good half hour to learn them. With vocab Lesson and Reviews, I don’t really try too hard, I’m happy to keep getting them wrong until I start getting them right.
I think the 1:3 Kanji to Vocab ratio is good. I play around with it a bit if I’m making good or bad progress, sometimes I do lessons in bunches of 6 and vocab in 18s, other times 5 Ks to 20 Vs.

There’s some more recent discussion about creating a schedule around the SRS intervals here: 


In reality, the guide’s pillars are mostly about creating a routine, habit-building, and helping people with decision-making on WK. I do teach how to go beast mode, but that’s a small part of it
