This morning I had a meeting with my boss. Today's meeting, on my part, is all about my exprimental design. I provided boss with metrics I planed to adopt in my expriment after careful thought. But boss did not like the metrics I put forward and asked me to turn to some metrics similarly like those used in his lastest paper. I listened and thought for a while.I think the metrics I prefer and the metrics he like are almost indentical in distinguish different categories, so I agreed with him.
