Thanks, that's a nice alternative to the trick I used. As to the CIs being different, I'm inclined to trust -margins- more than -adjust-. I suspect -adjust- was just doing relatively naïve delta method while -margins- is probably more sophisticated for the CIs, but I guess that's an RTM moment for us, really.
