Same experience here with my F100. After many incorrectly exposed frames, and a lot of studying to understand how it worked, I went back to CW. Matrix was just too unpredictable. The F4 doesn't seem as bad though.

And since the matrix mode has a mind of its own, literally, I found it hard to compensate so I just stayed clear of it.
