Re: Honorary or Earned???
I've had a similar experience, and I did talk about it with my teacher. His take on it was this.
1. Usually passing gradings ends up just being a formality anyway. People only attempt them once the teacher thinks they are ready, and if the teacher thinks you are ready, they will usually pass you no matter how badly you do on the day.
2. I think you are ready.
3. Now that you have it, make sure you keep training hard and prove that you've earned it.
I recently visited that dojo again after a year of training elsewhere, and the first thing sensei asked me was "do you wear your black belt, and do you feel like you deserve it?" and my honest answer was "yes". Training at a new dojo, I don't feel at all out of place with my black belt.
