CBC Test Design Report, why do I have effic of over 1.0 on some of my levels?

Is it possible to be that efficient? I thought 1.0 was the most efficient?

If the level appears more times than would be expected by a perfect level-balanced design, then it is possible to have higher than 1.0 efficiency for that level than expected by the "ideal design".  That means, of course, that other levels within the same attribute (factor) must appear less than ideal number of times, leading them to have less than 1.0 efficiency.
