"Perfect" or "correct" exposure is a misnomer if you're going (or think you can go) by some else's definition. The "right" exposure is what you intended to get, and sometimes your intention at the moment you released the shutter doesn't match with your intention for how you want your photo to turn out in the end. I know many of us try to (and often) succeed in visualizing the final output, but doing that over thousands of shots seems a little bit unrealistic. It can also be said that you can take the shot knowing full well how you will have to tweak it so that it turns out the way you intended. Getting it "right" in camera can mean intentionally over/under-exposing one part of the image so that another can turn out the way you want to, while you tame down the "blown" part in PP. So long as that was your intention and not a careless, shoot first, ask questions later mistake, that's acceptable in my book.
That said, I've been gratified at how little I've had to PP to "fix" exposure issues in the last few weddings. Consistency is good. It also can turn into "boring" so keep pushing.
