I believe the editor was trying to capture the scenario when traversing from a bfcache and not hitting the network, we shouldn't update the timing data for that page from when it had initially hit the network.

The definition of navigation, http://www.w3.org/TR/html5/single-page.html#navigate, which we are planning to reference in Navigation Timing, doesn't seem to explicitly call out session history traversal. Does this mean that if we use that definition of navigation, the bfcache scenario would be treated the same as document.open/.write/.close, which is that it does not impact Navigation Timing? If so, I think we can safely remove those sentences in Section 5.1.

Thanks,
Jatinder
