Agreed. That was added after I posted, but this is why I run a 48/34 instead of the more standard 50/34. The only thing a 52 gives you is a higher high end. At the same time it does that, it also makes the low end and the closely spaced range of the big ring higher as well.
I have never understood the people that say 52/36 lets them shift less up front, unless what they're really saying is they ride around more in the small ring, in which case older compacts like 50/36 would have served the same purpose just as well. With a modern cassette, usually bringing a chainring closer to 39-42t will mean you won't have to shift the front as much. You diverge from this to get lower climbing gears and higher downhill/tailwind/sprinting gears.
