Default is output_default = raw_model + be_kiss_a_system When that gets changed by the user to output_user = raw_model + be_kiss_a_system - be_abrupt_user Unless be_abrupt_user happens to be identical to be_kiss_a_system _and_ is applied with identical weight then it's seems likely that it's always going to add more noise to the output.
