I can't seem to find the internet source that discusses this in detail.

It is worth remembering that the flash metering system is heavily weighted toward the center of the image.  I have found my results with CLS greatly improve when I put the subject in the center of the frame and use FV-Lock in TTL mode.  Then, when I recompose the flash component doesn't change.  If the subject is off center, your results with CLS TTL can be all over the place without using FV-Lock.

I was thinking CLS switched between TTL-BL and TTL when the metering was changed from Matrix to Spot.  However, I can't seem to locate that in any manual, even though I thought it was.  I must be mistaken on that.

Here is the best source with lots of comments and discussion:
