Are you talking about site: operator numbers? They are quite variable with no real impact on your traffic.
In fact, if your url structure use sub-directories, you can see something quite odd. Just get all the numbers for this kind of search: site:example.com/subdirectory-example, then add them together. In many cases, you'll see a higher number than site:example.com. Not only that, but the URLs are sometimes all listed for you.
A quicker check can come from the xml Sitemap indexed numbers from WMT - when that one's not acting up.
I prefer other metrics - total urls the googlebot is requesting, ir even better, the total number of URLs getting search traffic.
