What do you want to see next?

FWIW, I do have TCP retransmits over the life of the page load (as well as packet transmits so you can calculate a rate). It's in the raw page data (link in the top-right of the results page). That will at least tell you if you had any packet loss during the test but not on which connection. It doesn't detect inbound packet loss but that's a lot harder to detect, even with raw access to the packets.

On the (very long) list of things to do is to capture the packets from a test which will allow better analysis (and more accurate timings on the network-view of the traffic).
