Fellow speaker,
World Champion speaker Ed Tate scores his written out speech according to audience participation. He writes a "1" for the places in the speech when he's talking alone, a "2" for when he's talking with audience participation and a "3" for when he's talking with audience participation while some kind of visual (such as Powerpoint) is going on. He then tries to balance out his speech so he doesn't bore (too many "1"s) or tire out" (too many "2"s or "3"s) his audience.
Balancing it out,
Tim
