Wow, Chris, that's really really wrong, like stick forward houses smaller.
The dome is pointed at the lens. It then averages light falling on the
subject. If it is pointed toward the light source, it will consistnetantly
underexpose, as it isn't allowing for the fact that light is not falling on
parts of the subject.
The proper use of an incident meter is one of those elegantly simple things
that works almost every time, and gets better results than the most
sophisticated in camera metering systems. The ultimate use is in
cinematography, where each shot must not only be well exposed, but match
lots of others.
