Dear Manuela,
you are right, your importance biasing is not working, because by default
it is applied only to prompt radiation. In order to activate it for decay
radiation, you have to properly set WHAT(4) of the RADDECAY card (see the
manual), which is rendered by Flair in a more convenient way.
Best regards
Francesco
