Defining the contours of the topic for a lec-dem given a certain duration is something many presenters have difficulty with. A circle needs to be drawn defining the centre (the core message) and the radius (the sweep of coverage). Some of the lec-dem presenters do not focus on these aspects sufficiently. Like a concert, a lec-dem also requires a good kalapramana – so if the topic is to be completed in the given time at a certain tempo, it needs careful planning. The optimum duration for a lec-dem though needs some debate.
