So I just got 2nd dan, and I checked out my achievement.. then the thought struck me: "I wonder what the breakdown of belts looks like.." So I made a chart in Excel to show how many people have each belt achievement, from white to 10th dan. Master and Custom belts aren't included, because there aren't achievements for them.

Here's the data:



There are 3.7x more white belts than orange belts, and almost 500x more whites as there are 10th dans. How about that success rate!

I just thought this was interesting.
