how does your stats package count page loads?
if it is using javascript, then it won't count until the javascript is loaded and executed.
if the javascript is just before the body tag, it won't start executing until the whole page has loaded.
just some things to think about.

if you want to look at page load times there are several tool available for measuring things and some make suggestions for improvement.
i would suggest starting with the open source firefox add-ons called Page Speed and YSlow! and see if those provide some clues.
