Just something to think about.
I've had the same experience as you. The master/controller setting does make a difference, but the popup flash does indeed contribute to the exposure, even at the controller setting.
The Nikon accessory is a nice solution. You can also DIY it with tape and a pocket mirror, a business card etc.
