Why in the world would anyone need 10" of crankcase vacuum? Especially on a street car?

I realize a pcv can draw that much, maybe, but still see no benefit from 10". Even with super light rings, you don't need that much. That's why most only draw a couple inches.

I was under the impression that people who do 'need' to run them are blow-thru cars, but I could be mistaken. Maybe I need some schooling on that...
