Franchise Research Institute ... how good is it's research ... really?

I ran across the "Franchise Research Institute" today and wondered what the quality of it's research really was or at least what people have experienced and/or heard.

Is it's work independent of the franchise they evaluate?

Are it's research methods valid/reliable?

How can one misinterpret this outfits research findings?

Pointers to other quality sources would also be appreciated.

Thanks.
