Could it be that the camera changes from matrix to centre weighted meetering when switching to manual? Check EXIF data!

I was checking the results of a CLA on one of my lenses. Mounted the DS securely on my desk, set and locked exposure to 1/60 sec @ 5.6 with ISO of 200, took a few snaps of the wall. This was in Av mode. Changed to full manual, exposure set to 1/60sec @ 5.6, 200 ISO. Exposures look to be about one stop apart. Results like this are unacceptable. Tried the scenario a number of times, making sure to hit the AE-L button, making sure settings did not change, etc. Must have run through 50 or so exposures testing this. The camera consistently under exposes when in manual mode compared to using the same settings an Ap Priority. Any thoughts? Shel "Am I paranoid or perceptive?"
