KMDL has been the market leader for some time now. But that report doesn't tell the full story. It includes all persons 12 and above. Every station has a target demographic. KPEL-FM, for example, shows up as number 11 on that report, but if you narrow down to Men 25-54 (the target demo), that ranking obviously changes. When I was PD in 2013 and '14, KPEL-FM was consistently in the top 5. As of the spring, it looks like that may be the case again. There's a lot more (even than what I described above) that goes into analyzing ratings and determining a station's true market position.
