Cpl Clott, this is not how surveys work. For example:
45% of the RAF are satisfied with their Single Living Accommodation. Ie. 55% are dissatisfied with their mess accomodation.
You can't use the headline figure to conclude that 55% are dissatisfied, however tempting that might be, because the AFCAS questionnaire, like many surveys, uses normative questions. So whilst 45% are satisfied, what you won't know is how many are 'neither satisfied nor dissatisfied'. It could well be that 55% are incandescent about the state of their mess accommodation, but it could also be that 30% are ambivalent, so only 25% are actually dissatisfied. You need the detailed breakdown to avoid drawing false conclusions.
You could be right in all that you say but based on the stats alone you might also be wrong - 50% confidence in achieving (eg) a delivery date can be interpreted as either yes or no, depending on how optimistic you are.
