One is always trying to ensure that there's some sort of quantitative or directional assessment of performance. If there's a defined target, how do you determine how far you've gone in meeting that target? You know that if the target is defined quantitatively and 100% of your requirements are met, then it's fully met. But if it's part of the way, we need some way of trying to calibrate that; so we said “mostly met” if it's a majority.
