remember that people can be testing from a laptop tethered to a phone.

I think that showing the spike is significant because that latency spike would 
impact the user. It's not false data.

showing two graphs may be the way to go.

I don't think showing the 95th percentile is right. Again it is throwing away 
significant datapoints.

I think summarizing the number as an average (with error bands) for each 
category of the test would be useful.
