I used a fiddle in case anyone wants to play with that. I'd love to help integrate client side performance testing into an extension/experiment or whatever else you guys deem useful.
1. doesn't show up in the Network tab but it's basically 4. plus the time to load all the resources. In jquery speak, timing.loadEventStart is the number of milliseconds since 1/1/1970 that $(document).ready handlers would fire.Sorry, 1. = 2+3+6+4+5+(load all resources). I think :)
