The Stats page (https://www.beltchecker.c[...]hp?p=belts) at current verified sample size shows a very close average time of 3 years spent at every belt from White-Brown. It'll be interesting to see if the average only gets closer to 3 years as more and more get verified. For every 3 month White->Blue you see, there's some ronin white belt grinding away for over a decade out there somewhere. Interesting how that works out.

Yeah I was also surprised to see how close every belt promotion average is to 3 years! Numbers are beautiful sometimes :)

unless those numbers are in the negatives on the old bank account.

I hope Christian will have time to draw some more data about the belts in the near future.
The true average seems to show kinda boring similar times for every colored belt for the reason you mentioned, "for every 3 month White->Blue you see, there's some ronin white belt grinding away for over a decade out there somewhere" and this skews the actual average time of getting the belt.
I'd like to see median times, some age & country related data, perhaps a more detailed distribution how the years spent at each belt are distributed etc...
Personally I keep grinding on my 3 years / a belt path & contribute making the stats stay boring... :D

Ha - well, I spent around 3 years at blue, but apparently doing my best to skew the stats for all the other belts so far. 1 year at white belt, almost 7 years at purple, we'll see how long at brown (2 years so far). ;)

And that makes 12 years to BB for a "average" BB and I think that is pretty reasonable - if you are an average thorough hobbyist who has their fluctuations in attendance but are thorough and meticulous through that time you'll be pretty darn good. And then you have your pure athletes who do it shorter and everyone who has some breaks setback and for those it takes longer.

Is there a way to depict gaps in training?
My profile shows I was a purple for 8yrs 10mos, which is accurate by calendar promotion dates -- but as far as training, I was on active duty for a majority of that time and not training. In reality, I was actively training as a purple belt for just at 4 years.
I don't want to unintentionally skew the stats. If there isn't a good way already (besides a comment under the belt), I think there should be a way to put in gaps in training. That may solve some of the 10+ year white belts in the stats.

I guess, although I think having those breaks included doesn't stop it begin an accurate reflection of how long it takes to get a belt. It's pretty common for people to have breaks, as life often gets in the way and BJJ progression takes a long time.

I think it makes no sense to put the gaps - it creates too much grey area. E.g. I was a purplebelt for nine years. But firstly I got my purple real quick (3 years) and secondly I focused on MMA for the most of the time I was a purplebelt. My jiujitsu stalled because that was "good enough". But I still trained a lot of wrestling, occasionally put on a gi etc. And then I had a kid... Was that a training break? I guess not :)

I can see that argument: as long as the break was somehow included too, I guess that's still accurate. I like grey areas, black and white is boring. :P

Sounds like you didn't really STOP completely.
My argument is for people with legitimate gaps between belts. For example.
Sam started training in Jan 2000.
In June 2000, he got injured, had a kid, and moved to another country (extreme, I know). He didn't continue to train.
In Jan 2014, Sam started training again.
In Jan 2015, Sam received his blue belt.
How long was Sam a white belt?
A) 15 years
B) 18 months

Though I'd say that Hypothetical Sam is probably a very different blue belt to somebody who simply trained 18 months and got their blue, with no breaks. Having that experience of BJJ in the year 2000 makes a huge difference for a start, I'd say, particularly the kind of techniques Hypothetical Sam would have been taught as a white belt and the environment he's likely to have trained it. Also possible that he still did something related during that break, perhaps headed down to judo for 10 years, took up MMA, continued to stay peripherally interested in BJJ, etc. There are different kinds of break: some are complete, so no BJJ, nothing related at all, some not so much.
So, I'd still view them as a 15 year white belt, not an 18 month white belt.

Very nice example, I had a friend start Bjj before me and then quit, now come back and act like he is 7 years White Belt aka “I should be Blue Belt at least”

From a technical point of view, it can get way too complicated to implement gaps at scale. At least how I look at it at this point with the current calculations of stats. So for now, it is what it is.

Did someone take away Sam's whitebelt while he was injured? No. Therefore he is a whitebelt for 15 years and that's honest.
Mic drop.
(I currently haven't been training for 2 weeks due to myself and the kids being sick, life etc... life still goes on... noone's going to take away my blackbelt even if I stop training for a few years and returning to mat all the decent blues kick my arse...)

I think it might be more illustrative to show median time between belts, not average (i.e. how long did it take 50% of people to get promoted). That will take care of extremes skewing the overall stats.
It would be good to see 90th percentile in addition to median as well (i.e. how long did it take for 90% of people to get promoted).

Oooh... I see you too are a man of cul...statistics :) That's a good idea!

Reminds me of a quote (and I'm paraphrasing here):
Q: How long does it take the average person to get a [BELT_RANK] in jiu jitsu?
A: The average person does not get a [BELT_RANK] in jiu jitsu.
May sound somewhat elitist but I think it's true.
We are a rare breed! :)

It's been 12 years of training from me, and I fall into the same numbers as most others it seems. Because of beltchecker.com I actually went through and looked at each date of my promotions and I spent 3 years each at Blue, Purple, and Brown.
It felt like I was at purple for 8 years and then just got promoted to Brown lol.
