Why not? Their system simulates latency between their facilities in two cities. Latency does not change much. Their solution adjusts to realtime latency variance, but they don't show that such realtime adjustment is needed. The article doesn't say whether they even measured latency variance.

And they also don't show that their dynamic adjustments are more fair than a static adjustment. I think it's likely that their system penalizes local players for too long after a short remote latency spike.
