The thing about anecdotal evidence is just that- anecdotal.
I for one would love to see not only a disection of the filters, but some sort of lab testing of filters including:
1. filtration and flow new
2. filtration and flow after simulated 3000 miles (heat, contaminantsa and all)
3. same after 7500
...and if you go longer than that, you just don't care IMHO
This would have to be done with many samples of each filter to ensure no statistical anomolies.

As an aside, we all have know someone like Uncle Ted who used a Fram every time and ran all his cars over 200,000 miles, or Cousin Bob who used a Fram and threw a rod 3 weeks later. There are so many variables
