PPM vs Minorities

R&R just noted:
>>NABOB has joined other minority-interest groups by filing a petition
with the FCC calling for
>>an investigation into Arbitron's PPM.
As I understand it, with the PPM, minorities' listening habits don't
match those reported under the diary system.
It would appear that the results are significantly different. Which I
would expect, since the PPM is supposed to be a better measurement based
on actual listening vs what a diary-keeper can remember.
So, what's their beef? Are they claiming that diaries are statistically
better than the PPM and that Arbitron has created an electronic device
that discriminates against minorities?
