That's bascially how the two are related.

Then the meter has the extra work to try to back out the optics of the meter and factor in the optics of the camera and estimate the camera flare. (while an in-camera meter is excused from some of that work)?
Yes, hand held exposure meters have to estimate the value of q, while in camera meters measure the actual luminance passing through the optical system.
