Yah... Chris, I thought I remembered someone mentioning in another post about wanting to get some numbers for comparison, but I wasn't sure if it was you or not.
As far as the actual flow rate, I think that for comparison purposes it is better to go with the factory flow ratings since they are what is typically published, and then just remember the 5x/hr. rule of thumb.
You also have to remember that actual flow rate is going to be different on a case-by-case basis because of differences in filter media used (type, brand), how it is laid out in the baskets, and how dirty the media is (i.e. how long since it was last cleaned/replaced). As a result, actual flow rate will differ enough that it may not be as reliable a method for comparing different brands & models.
