It's easier to make a 3-inch mirror and a 5-inch mirror, than to make a 5-inch mirror." I know this as referencing 6" and 8", which makes a whole lot more sense, since a 3" mirror is tough to make (because it's small and fiddly). I don't know who first said that, but speaking as someone who built an 8" mirror first, I would have to say they are probably right :-)
