Webpagetest & Other Browser data donot match

[pmeenan]

Do you have a link to a test result? Sometimes Chrome and Firefox will show resources served from cache as well as Data URI's as requests but WPT only includes traffic that actually hits the network.

Presumably the number of requests change because there is some content on the page that is dynamic (in the case of kohls.com's main page it looks like there is an adsense ad near the bottom for example which will be different every time).
