Um, David, 104.1 is WHTT - hardly Buddy's most important "translator." Early on, Buddy patterned much of his station after the former "Oldies 104.1" which moved on from oldies and is now the leading Classic Hits station in the market.
Ah, I get it. Buddy is complaining that there is/are split diary entries where they, for example, give his slogan/station name and someone else's frequency. He did not explain that, and I'm still working on memorizing the calls and frequencies of all the new translators...
In that case, Nielsen has a long-standing (over 50 years) practice in allocating "mixed credit" entries. Things like call letters of one station and slogan or talent of another. Or "107 FM" when the market has both a 107.1 and a 107.7 that are local.
In that case, they do not throw out the entry, as that would reduce the PUR for the market, which is bad for the industry.
In the case of an entry like Buddy mentions, they take the trailing average share of WHTT and the the trailing average share of WECK, and establish a proportion. Let's say WHTT has a 5 share and WECK has a 2.5 share, then they give 2/3 of the credit to WHTT and 1/3 to WECK. This prevents the confused diary entry from changing the results, but allows it for market Persons Using Radio.
It is a bit more complicated, as the formula for attribution varies according to the age, gender, ethnicity and daypart for the confused entry, but my explanation shows the overall treatment.
I've seen very strange diary entries over the years. In one diary in Chicago from an "ultra" senior an 87 year-old non-Hispanic put down "WIND" which was our Spanish talk station. But they put down the name of a deceased talent who had been previously on WGN along side of the WIND calls. In that case, 50% was credited to "UUUU" (Unknown) and 50% to WIND although logic said that the old guy with a Polish name was not listening to a Spanish station. In these cases, they do not make decisions based on logic, only on what is listed in the diary: a dead guy (no credit to anyone) and actual call letters (valid).
If you think about it, the system is logical and can handle any strange entry without decreasing the market PUR.
