That doesn't take into account the performance of the CCD, or the analog
front end, or the actual converter performance.  Do you have any idea if the
manufacturers actually do any testing to conclude that what they claim as a
spec, is how the system actually performs?  If they are basing their specs
on purely empirical data, then they are not, in my book, really accurate
specs.
