Ratings Double Counting

For years, the AFL following ratings watchers have decried the NRLs “wins” in regionals by claiming that there is some significant double counting in regional/metro areas. The hell of it is, it does seem to be true to an extent if you simply look at the postcodes.

HOWEVER – and this is for the people who keep referring to this – it should be noted that RegionalTAM expressly says that ratings from RegionalTAM and OzTAM can be combined to form an aggregate, and im not sure that this would be the case if they were double counted.

I have some reservations – namely we simply dont know whether a person counted in a spill area is counted by both regionalTAm and oztam – the RegionalTam site goes to great pains to point out they are separate commercial entities with their own data sets. At this time im waiting to hear back.

Affected postcodes are below.
