You've got nothing to loose. State the actual amount of hours you have, and if 80 hours less than the requirement is something they can't get past even though you will exceed it probably by the time you do the assessment, well, at least you've tried.
Much easier to explain to the person in the room why you applied without meeting requirements compared to why you falsified your CV. If they have at least a bit of common sense, it shouldn't be a problem.
