As my "contribution":

- try to define accurately the questions you post, otherwise it is possible to get a wrong answer;
- you can have "actual" values when define "actual events"; a modal analysis can get only a basis of calculation (let's say eigenvalues and eigenvectors- basis in the vector space); what I suggested there was to transfer to vendor (if it is the case!) that basis of calculation when Vendor is not able to understand that you cannot have actual results without defining the vibrating phenomenon.
