Yes, I know all this. I might not have gone to school to become a machinist (sounds like you have?), but I have had plenty of stuff machined that had both press fits and slip fits. I think of a press fit as requiring a hydraulic press to assemble, which is definately not required here.
But, you are right, I was mainly talking about the loose tolerances of Mazda's machining. Might also have been due to the races spinning and eating away at the soft aluminum.
What are the pics that you attached? They are too small and I can't make out the writing.
I also failed to mention that my setup for the secondary inner bearing was unique anyways as I used a race that had an outer lip and also welded in a support plate in the bellhousing right behind it. This caused the bellhousing to warp a little and I had to get it remachined to fit the race and lip. That opened up the clearances by a few thou.
