I would say that it is missing 'a lot'. If this is the case, then in Britain it could mean that there is a lot still to be done. We Brits often use quite to mean something similar to 'very' or 'a lot'.
How was your weekend?
It was quite good (meaning I had a lovely weekend).
Perhaps this is due to our apparantly reserved nature. However, quite can mean quite. It is an issue of pragmatics, what is conveyed above and beyond the literal meaning of the word(s) expressed.
