Re: Seiza by ranks?
This is a good question. At my club, we tend to line up with those who tested first higher up, but in saying that, the trend tends to be towards the person who attends more frequently. So a 2nd kyu who tested a year before another 2nd kyu, but has had a 2 month rest while the other aikidoka has been to every class, will most likely sit beneath the newer fella.
Its a kind of recognition for commitment to training I guess.
No hard and fast rule on that one though.
