One reason I have asked about how ranks transfers between dojos and organisations, is not because I'm fixated on "holding a big rank" between jumps. Rather (and I have pointed this out in the past), I want to avoid unnecessary problems in teaching for different things and grades and ranks.
I think this is where most of the confusion arises. In every dojo I have trained in (4 styles, 2 countries) there is no distinction between what is taught to people at different ranks. The higher ranks are just better at it, that's all.
