Would you say that weeklies are playing the same role that extraps did with the diary? Do agencies look at weeklies or is it considered too small of a time frame to make decisions with?
Agencies don't get weeklies, and as far as LV is concerned, will not get PPM data until January.
Extraps had little validity, even at the station level, as they represented a fraction of the sample and were unweighted.
Agencies that have been trained know that the weekly sample is the same size as the monthly, quarterly or annual sample... so they will look at both the most recent month and ongoing averages (for stability).
