Iāve heard it gets hard after 30 
Hey whatās the script you use to see the breakdown of levels in apprentice and guru?
It will take a while before I will get there but I already know I will keep my normal tempo. Doing those level in 3 or 4 days is way too crazy for me 
Not many levels to chart yet, I doubt Iāll be able to keep up my current pace for the rest of the levels (the more complicated looking kanji and radicals of level 4 are already tripping me up and slowing me down a lot haha 
).
The first increase is when I went from 20 items per day to 15, and the second increase was when I went from 15 items per day to 10.
Level 30 was also about when I began to encounter a lot of vocabulary words I was not familiar with so I slowed down in order to increase my accuracy level. At first I wanted to āfinish right awayā, but then realized that it would be better to go slowly and actually remember it than to just rush through and forget everything right away. If I donāt use it Iāll definitely lose it.
Iāve slowed down lately partly because Iāve been reading more, partly because Iāve been having difficultyājust with getting myself to do my reviews, though there hasnāt really been a notable drop in accuracy. I tend to do level-up reviews and then burn reviews before chipping away at the rest, so Iām still making progress. Did not realize Iād taken nearly 41 days for Lv 21 though, thatās a lot for me.
These are my current numbers, with 66 lessons (just unlocked a bunch of vocab from the second half of Lv 23) and 162 reviews:
(Free levels grayed out because I wasnāt really sure I wanted to pay for the service quite yet, so I wasnāt nearly as committed)
My progress so far. I absolutely DO NOT recommend doing the 6 day 20 hour levels, they really mess with a normal sleep schedule. (Good thing I never had one.) Iām coming up on the shorter levels soon, lets see if I can keep the pace up.

This is the way.
The variations are basically me being lazy and not levelling up first thing in the morning for the 4 + 8 hour reviews. The less than ideal situation is that on next level up I canāt do the A2 4 hour review before bed so that I sleep through the 8 hour wait to A3, but at worst Iām a lazy bastard and do the A2 review in the morning.
Regarding speed run, itās a matter of studying in advance, as well as having a good memory trick. (Simply repeating a lot, unofficially; and making/changing mnemonics for me.)
Nonetheless, I think extending a little (to 1-4 weeks, for example), without breaking or losing momentum, is a skill I didnāt have. I was pretty much č”ē¼, canāt take my eyes off this, (rather than perfect time for new items, and do immediately).
Iām sure youāve heard it a million times but Iām also of the mind that consistency is the number one thing you need - I have been in love with consistent daily lessons since level 15. The 5 resets that I did definitely taught me a thing or two about what happens if I take a āshort breakāā¦ All I do these days is hit this button before my morning lessons and try to do reviews as often as possible and WK is great.
Anyway, your pace seems very similar to many other peopleās level up charts that Iāve seen, keep it up! 
Thanksā¦ I had no idea this was even a thingā¦ then againā¦ Iām ānewāā¦
A bit weird maybe, but on level 59 I procrastinated leveling up to 60ā¦ Had to ęŗå my kokoro.
As for the beginning, I finished the free levels and was waiting for the next month of student loan payment to come around so I could pay for lifetime subscription 
In retrospect, I shouldāve paid for a 1-year sub and waited for Christmas sale instead so I could get cashback thingie or what to call it. Either way, money well spent imo.
