> Always do at least 1 full rehearsal with a timer, preferably two full rehearsals Personally, for me to feel very comfortable in delivering the talk, I practice the whole presentation at least five, six times. The first couple of those practice runs, I tend to adjust the slides and my talk, to iron out the wrinkles in either my slides, my words or the transitions/logic between the slides. The latter practice runs are essentially to memorize the whole talk. I typically write out my whole speech in the speaker notes, but after two-three practice runs I don't need to look at them anymore. The result is a presentation delivery that as an intronerd I'm very comfortable with -- even the jokes have been practiced and perfected -- and one that I could deliver practically verbatim the next day.
