I checked some glass that I've been using for newspaper stropping, and it's just as perceptibly flat as the plate, and the granite tile I bought at lowes for 5 bucks checks to be pretty dang flat, too.
So, for all you guys wanting a granite reference plate but don't have any where to put it or the $$ to pony up, just go get a 12" square granite tile from lowes. It's 5 bucks and does just as well as the flat reference slab. It just doesn't come with a certificate!
