This is what I have read as well.
I think that's overboard just a bit and then some there dude. I beileve it's no more than .010.
I just dropped mine in and got .006 at a max. I really leaned on the screw driver when I moved the crank back and forth to get that reading. Otherwise, just a good lean on the screwdriver back and forth to set it up I'd get .005.
