I don't want to be annoying or anything, but this diagram right here is just theory. There are no guarantee whatsoever that even if you use Azure's backbone network as the given example implies that you would get a flat 50% latency reduction, this graph looks extremely manipulative and false marketing to me.
Even if a possible 10% latency reduction was possible the above architecture is off-limits for the 99% of the live servers out there, making your share another educational usage project :)
