I would just like to emphasise that Stefan is absolutely right when he says "B format 1st order was not based on "FuMa conventions", it is obviously the other way around. ". Richard and I were looking at extending the naming of channels up to third order in a way that respected the conventions of the original B Format when we announced the scheme in 2000.
