Timing test question for thee geniuses

Hello. I was hoping someone here may be able to answer a question google has thus far been unable to answer. I have received the following information as the results of a 24 hour timing test on an Omega Seamaster. I am familiar with multi-position COSC results, but have not seen results in this format before. Any help interpreting them would be helpful. A link to a resource with more details would be doubly appreciated. Thanks.
