This does not mention if the tests also simulated and measured packet loss.

With a good network connection with little packet loss, I wouldn't expect much benefit to /3. Especially since all the server and client implementations are immature and in user space without kernel support.

The benefits should show up with (poor) mobile connections.

Thanks for pointing this out! I really wish the blog would explain that better. /3 will really shine where connection has degradation.

For me the most exciting part is the seamless network switching potential of /3 on mobile devices

IME cellular connections don't exhibit much packet loss. The lower level layer of the mobile network usually ensures that the packets are usually eventually delivered, they just take a while. This makes sense since internet protocols are designed to interpret packet loss as congestion and will slow down transmission when it occurs.
