TView: How does TView calculate Reach and Frequency?

Question: How is Reach/Frequency calculated in TView?

Answer: When a user defines a daypart in TView, the system builds probabilities for each person on whether s/he will see the next spot. This prediction is made for the number of times every respondent will be exposed to airings in your campaign. TView adds these up for the Demo defined in the plansheet. The totals created for GRPs, reach, frequency, costs, etc. are calculations based off projections for all of the respondents in your demo.
