What I saw happening is Wallace would ask Trump a question and he would answer, then the question was asked of Biden he used the time to attack Trump 90% of the questions. Then when Trump tried to rebut Biden, Wallace would shut him down. As much as both parties need to speak both parties need to answer the questions too. The next one if they want to turn the mic. off when its not you're turn thats ok but if you pivot from the question you are shut down and lose your time.
