You Need to Show Up Early

• debugging pattern recognition algorithms
• early detector checkout

On a mature experiment, Event Display's are used for

• inspection of candidate events for rare Physics processes
• public relations

The bulk of the use of an Event Display comes early in the life cycle of an experiment.

Event Displays are a case in which

• three people working full time for two years (3 x 1 x 2 = 6 person-years)
• is better than
• four people working half time for four years (4 x .5 x 4 = 8 person-years)
