Stewart,

does your Jason decoder try to keep track of symbol timing
or does it only wait looking for the next transition (as the native
decoder)?

If timing is important, how will slight timing errors affect performance?

You mentioned "symbol phase", do you mean MSNibble/LSNibble
or does the decoder expect the signal to be "phase coherent"?
