Occasionally there are objections to modifying complete with qualifiers like almost, more, most, nearly, and quite, because they suggest that complete is relative rather than absolute: an almost complete record; a more complete proposal; the most complete list available. However, such uses are fully standard and occur regularly in all varieties of spoken and written English. See also perfect, unique.
