Someone else already mentioned this, and I can't say we can be 100% sure, but it seems likely that each review is weighted by how far off the score is from the individual reviewer's standard deviation. This would render the scores themselves somewhat meaningless - at least in a vacuum (which, based on this forum, is a fair hypothesis anyway). So you may have gotten reviewers that were fairly generous reviewers overall. And those who got it with lesser scores (like myself: E/VG E/E VG/E) might have had reviewers who were generally harsher overall. This is basically the only thing that makes sense to me in parsing through the scores and results on this forum, but who knows!
That said, I can imagine they throw out anything less than "G" before the weighting occurs. I don't think I've seen anyone win with a F or P in their scores. I'm hedging actually, because I'm not sure I've seen a winner with a G either.
Food for thought.
