OK, your explanation is certainly as good as mine :-)

Off the subject: "decimated" is an oft-misunderstood word, . We tend to think it means wiped out, i.e. reduced to only one-tenth of its original size - but it's really much less virulent, and means reduced by one-tenth.

Do I see the makings of a theme? "Scan" is another misunderstood word, meaning not to look over hastily and superficially, as many assume, but rather to scrutinize carefully and in great detail. ("We're being scanned, Captain.") Can you think of many other words like these two?
