Interesting. We train more than 250 hours a year and it takes about 6 years to 1st Dan.

My reply is a little off-topic, but kinda-sorta touches on it, and your post brings it to mind. In the past we've often discussed going away from a multi-level Dan system. In place of it, use a training log system. For example, someone could say they've been a BB for 20 years. Okay, but what does that mean really? Does it mean they've consistently trained for the last 20 years? Or does it mean they became a BB 20 years ago but haven't trained three minutes since? This is where logged training hours come into play.
Let's make up some numbers just for discussion. Let's say it takes 500 hours to become a BB (as well as successfully passing a test). How one arrives at the required 500 hours depends on a couple of factors (the structure of the school and availability of classes and the seriousness of the student). Once the student reaches the 500 hours (or whatever the actual requirement may be), and they successfully pass a test they become a BB. They again log their training hours after this point. In this way, you can differentiate between a 20 year BB that has 6000 logged hours and one that has 501 hours in the same 20 year period.
Now one could also do the same with belt levels as well. Which brings us back to the point of what, if anything, is learned for each Dan level?
Now to be clear, I'm not saying it is wrong for an art to not have 'new' material after the first Dan and having 'experience' count for promotions. Just as it isn't wrong for an art to have new material for a Dan to learn at each level. As long as the art is clear on the point and the student is satisfied with whatever the requirements are to be promoted.
