A good communicator is one who offers the audience

A good communicator offers the audience plenty of relevant information.

Relevance keeps the message useful and connected to the audience's needs.

A large amount of statistics can overwhelm rather than inform if it is not relevant.

Only concise proof may be too sparse to build real understanding.

Mere repetition of facts adds no new value and tires the audience.

The quality and relevance of information matter more than sheer quantity or repetition.
