I don't know why PageSpeed displays -1, but note that there can be two types of cached requests
1) The server returns 304 and so the body is mined from the browser cache. These requests are displayed in the Net panel with status code 304. 2) The browser reads the URL directly from the browser cache without asking the server (there is no roundtrip). These requests are not yet displayed in the Net panel. But this is planned feature, see here: http://code.google.com/p/fbug/issues/detail?id=1208 Perhaps PageSpeed uses -1 for #2 ?
