network ping is not a fixed factor, also, faster hardware does not improve ping times. Furthermore, ping times increase as the network becomes more saturated.
then you run into issues of shared internet connections which is very popular today
overall, most of their response time claims are based on assuming a fixed nature of factors that are historically random and heavily influenced by the actions of your neighbors, distance from the server, and random issues or bandwidth management on the ISP's backbone
based on their claims, just having your ping go over 30ms, sends you over their proposed delays offered by current gen consoles (which seem a bit exaggerated (most likely a word case scenario since a 166ms delay is very noticable
anything above 20ms is very noticeable, ant 166ms for you to see a response to user input will be felt as extreme sluggishness
(you ever run a game that your system cant handle properly and the mouse cursor feels very sluggish but is still able to move smoothly (that sluggish feeling comes from the a noticeable delay in how it responds to your movement. When using the mouse, you are constantly adjusting your movement speed and direction and getting something like even a 50ms delay would cause a sense of sluggishness as you will constantly adjust your movements either too late or too soon
When you game your PC or console and it is running very smoothly, those delays are most likely well under 20ms
(PS understand that human reaction time is different from the amount if time delta needed for detecting a delay)
