[Plugin: WordPress.com Stats] Widget not pulling accurate data from stats

I am showing stats in a widget. The view numbers are off, but even if I omit the view numbers, when I compare to the stats admin area, the widget is skipping some articles for no apparent reason.

We are running WP 3.0.4 so we can’t try JetPack. It will be a while before we are prepared to upgrade, but if anyone can tell me Jetpack is the cure, that could spur them on.
