Sorry to keep you waiting. We just checked the test bar in house again but contact angle accuracy is within tolerance.Also, we visited mesuring machine maker (Tokyo Seimitsu, TVMK uses the measuring machine) and checked same test bar.the result is not same but it was similar comparing with TVMK data.(These datas will send you next week.) However, we couldn't reach why tolerance miss matching happen between TVMK and PMI.To check the reproducibility, we will send sample test bar to you and request to check the contact angle accuracy.Then, we would like to check the data is same as before (negative trend against TVMK data) or same as TVMK measuring data firstly.(*the test bar send you next week for FOC.) We would like to get the result we will study how to do next immidately.
