Previously, the message

no reference for prediction yet

would be shown, if the prediction made by the CMC was 0. With this Werk, the predicted value is now always shown. The prediction levels have been updated accordingly. * Absolute difference from prediction: 0 is treated like any other value. Some alarms, which used to be omitted, are now correctly reported. * In relation to standard deviation: 0 is treated like any other value. Some alarms, which used to be omitted, are now correctly reported. * Relative difference from prediction: Non-zero values are treated in a different manner. No dynamic levels are computed. This means the behaviour of this parameter has not changed with this Werk.

Note, the configuration In relation to standard deviation can lead to false alarms, if the standard deviation is zero.
