I think that this thread shows what I believe, that people try to define too much complexity into the game these days. For any of these short game shots, the goal is to carry the ball far enough so that the planned release lets the ball roll to the hole. It's as simple as that, and it really doesn't matter what you call it.
I have chipped many times from 50 yards out, and I've pitched a lob from 20 feet. It all depends on the circumstances. I will still continue to call it a chip when the carry is less than half of the total distance, and a pitch when it's more.
But the name doesn't really matter (Old Bill said it well, that a rose by any other name would still smell as sweet). What matters is that you practice all of the varieties of this shot so that you can select the correct shot when needed.
