Article author here -- I agree, it would be interesting to see results. One reason for using more than a single image: no navigation timing API in iOS.

iOS may now lag behind Android in handsets shipped -- but it's still a dominant player in web visits on mobile!

Unfortunately that means that for RUM tests I needed to have results that were insensitive to differences of a few ms.

Here's a petition asking Apple to include the navigation timing API in a future iOS release:

As someone who is grateful for your research and analysis, thank you, but filing a bug report is going to be WAY more effective, at least for iOS. https://bugreport.apple.com/ will get the ball rolling, even if it's been filed already. The more reports they get, the more likely they'll look at fixing the issue, especially if good use cases are provided.
