It really depends on what you are trying to accomplish if you need to worry what Google is reporting with respect to the page load time.
In general, it's always good to pay attention to page load times, regardless what Google finds of it!
You can experiment with Asynchronous calls, or slow load jQuery scripts, which kick off after the headers and html framework already have been loaded.
Overall, I would not worry about the reports in Google WMC that much, just try to get faster in general.
If you are serious in delivering an ultra speedy service online, there are services which can test your site or application on multiple locations, different OS and connection speed or using a different browser.
But these services are pricy, trust me on that one!
