Your main job as a presenter is to ensure that throughout your presentation, you and everyone in the audience remain on the same page, even the same wavelength, every step of the way.

People process information at different rates; faster processors will take a shorter time and the slower processors will take longer. Before you know it, you’ve got an audience working at three to five different wavelengths at the same time.
