No, it won't give 1/10 stop precision over a 9 stop range. It gives you 1/3stop precision over a 6 stop range, just as CLS would. The advantage over the AC3 is that you can adjust all the flashes from the subject position to nail your exposure and lighting ratio without trial and error or chimping. Then too, CLS meters the flashes individually and not collectively.
Don't get me wrong. If I had a studio, I probably wouldn't even bother with PocketWizard. I would get the Einsteins with the CyberController.....no doubt. I'm a huge PCB fan.
