Started in April 2013, got to level ~24. Quit due to life getting in the way, and eventually came back to 2k reviews (before the vacation mode was a thing). Decided to reset my level to 5 and have been steadily working my way back up (just 4 more!)
So about 4 years now?
How do you get the data though, are you just manually recording it?
Those graphs all come from idigtech the Stats site.
Around 6 months, took me a while to get used to developing the mindset to remember kanji and the associated vocab since I started WK after about a week of starting my Japanese studies but once it clicked, Iāve been leveling up at a pretty consistent rate since.
Heās asking Kumirei about the graph made in google sheets. I assume Kumirei manually recorded those SRS levels by date.
Clicking Kumireiās avatar on mobile failed to bring up the post he was replying toā¦ ļ¼ćļ¼ļ¼æļ¼ļ¼ć
Took me 540 days to get to level 24, but I gave up once at level 11. Iāve been back to it and making steady progress since. Doing my levels in exactly 7 days has been a little bit of a game, I like the regularity of it, and every saturday is my big kanji learning day, which is convenient for me. I only use the reorder script to learn the radicals from my new level, otherwise no reorder and I try to do my current level reviews on time (if you do your reviews on time, I think you can do it in 6 days 20 hours, I did it in 6 days 21 hours once, but that means you have to wake up during the night once during the week). At the beginning I just had no idea how this thing worked so I kind of followed the flow, but there is satisfaction in understanding how the system works and trying to progress as fast as possible. I donāt feel like Iām burning up at the moment, I heard reaching level 30+ starts becoming really tough on numbers but so far so good.
Iāve just reached level 16. It took me 13 months - I blame my old brain, itās almost 72 years old! 
Thanks! I try to do my reviews as soon as possible so I can move through the levels.
You and another person have slices of cakeā¦
I was just wondering if you knew where they came fromā¦?
Yeahā¦ I want cakeā¦

Probably cuz today is my 1 year WK anniversary 
Oh, congrats!
That makes sense.
It says on the analytics that on level 16 you can understand more than half of the NHK EZ, Half of the books, twitter, news and wikis. Do you people that reached level 16 feel like that?
Understanding more than half of the kanji doesnāt mean understanding half the vocabulary, and both also donāt mean understanding half of whatās going on. To give an example, Iām going to write a sentence thatās been translated all directly into english from my other main language, hebrew, except for one word Iāll hold back:
āIt was difficult visiting the hospital for again after I overextended my ×Ø××.ā
Now, you might think whatever, this is any part of the human body, maybe a joint of somesort, except for the fact that the specific phrase ā×פש××Ŗ ××Ŗ ××Ø××ā (to break a leg[by overextension]) is actually the figure of speech used to mean that someone has gone into bankruptcy.
Itās the same with Japanese, in particular with kanji like č¢«, which can have meanings as separate as āincur damageā and āwear a hatā depending on what kanji it is or is not paired with.
Speaking from my experience as an English teacher, we donāt recommend independent reading books for children where they run into more than 3 words per page they donāt understand (ie: roughly 1 word out of every hundred). Granted, those are for children, who are less likely to be motivated overall, but still, I would say for an adult that if youāre running into more than two or three unfamiliar words per three sentences, youāre gonna have a hard time making sense of it, which Iād estimate to be about 3 in 36 words or 1 in 12 (1 in 10 if you prefer even round numbers.)
TL;DR knowing more than half of anything isnāt enough for reading comprehension; for that you really need to know about 90%.
Apparently Level 1-10 Kanji have so many vocabs that WaniKani didnāt teach. I can see that when I started looking into JLPT vocabularies.
Also, donāt forget non-Kanji vocabs, or even Wasei.
When I am getting used to it, Preview can crop pictures as well, but not very intuitive.
I forgot to count days ā excluding lv 1, it is 435 days, or 1 year 2 months 9 days.
Including lv1, it is 4 years and a half.
It took me 44 days to reach Level 8 (Iām on Day 48 now). My slowest level up time has been 7 days 18 hours. Hopefully I can keep it up. 
Completed level 50 yesterday after 808 days (which is about 2 years and 2 months). Probably going to take a short break before blitzing through the final ten levels. As in not doing any more lessons and letting my Apprentice count hopefully settle.
7 months, about 25 days per level.
