If I were a pinhead consultant, I would tend to compare this book to the same time last yr book (Feb-May '13 vs Feb-May '12) to gauge a station's success or failure.
Under that formula, the big 3 gainers would be Rock 101 (+2.2), JR FM (+1.4) and NW (+1.1). The big 3 losers would be QM (-1.2 irregardless of Christmas FM), The Beat (-1.1) and The Fox (-1.0).
AND, if I were the consultant for JACK-FM I'd be worried about the flatline ratings they have year over year.
Other comments...an uptick on country music....REALLY? Despite all the bad raps they get NW gains a point vs 2012. And, granted they are bankrolled by us and not paid advertisers, both CBCs are holding their own.
But the numbers crunchers will provide a slightly different formula, telling their advertisers they're #1 in the key demographic of 25-34 female with a wooden leg, lisp and hearing impairment.
These diaries should be able to pick up when people are listening to other forms of music (i.e.: smartphones) as I'm sure many people choose to listen to their own mix without some stupid station I.D. coming on every 4 minutes reminding you what station you're listening to, nor getting that big-ass 5-8 minute commercial cluster before the next 60 mins of music (and it seems EVERY station plays that big-ass cluster at the SAME TIME)
