Hi there, for the last 5 years belt has not shown your skill, but rather your experience. Most people don't look at your belt level and assume how good they are, since most people who stick around usually get into replay making.
Also, while brown belt is still a great achievement, try sticking around to get to 5th Dan, or even as long as tripstone and select others, who have played a whopping 50,000+ games ;)
