Some people will misunderstand you whatever you do. That doesn’t mean that you can’t or shouldn’t communicate more precisely with everybody else. Some people will notice.
If I (correctly) expect to be misunderstood, then the precision is only in my head and not actually facilitating communication. It can still be useful, if it’s recorded and I can call it back up later for some purpose, but otherwise it doesn’t help me or whoever I’m talking to. At worst, it ironically brushes up against knowingly misleading people.
