Ya, my Ca is good, I've always kept it around 390 -410. Anything over 360-370 is fine in a stable system, the advantage of having at 420 or higher is just as a buffer zone incase of a spike downwards.

I could probably feed the fish more, but again, I don't think that's a major contributor. I recall one member that used to come here had one of the nicest tanks ever, and he almost never fed his 3 or so fish. No supplements for the corals either....
