 During the Portland Center Stage run of his musical "Somewhere in Time", Davenport used dial-testing to partially gauge audience reaction.Although dial-testing is common in film and television, Davenport was the first producer to use it for the stage.While dial-testing is a controversial issue in the Broadway community, with some believing it will create formulaic theater, others see it as a useful tool, as detailed in the "New York Times" story covering the testing of "Somewhere in Time".
