Hi Kevin

The spectra are dynamic like you say, are the strong emission lines early on due to mass transfer from the red dwarf onto an  accretion disk around the white dwarf, causing disk instability and increase in light.  Or does matter impinge onto the surface of the white dwarf increasing  the systems light output, or is it a bit of both.  Probably am i right in saying its a little more complicated than that.  Anyway nice piece of work
