Automatic reorder level change when executing it twice

Hi,

When I create forecasting view I only fill the forecast model “automatic” and selection procedure “2”, after the first run some additional settings are fill by the system (model selection, optimization level, alpha factor, delta factor)  and if I run forecast again the values (reorder level) change from the first forecast value. Regading to this when executing in mass mode should i do it twice in order to get a more accurate forecast value or should I fulfill more values in forecast view and obtain the same reorder level even if a excute it twice.

Thanks
