When you say that Vistacoms system can display results instantly, is it really instantly?
Yes. Once the votes are in and the countdown clock has expired/moderator has asked for the results, you are a keystroke away from witnessing the results. The only time lag is for the audience members to mull over the selection of an answer and to enter their choice on the keypads. Experience has shown that approximately 10 seconds is an adequate amount of time for the entire audience to enter their responses.
