1) The <i>likely</i> worst-case trip time to the chat server is 250ms. [0] It&#x27;s true that that&#x27;s ~2.5x slower than the typical minimum human reaction time, but it takes a fair bit longer than this to type &quot;top&lt;enter&gt;&quot;. [1]<p>2) The case where the server displays one message ordering to one player and another message ordering to another player is strictly worse than the case where the server takes 250ms longer to display the same message ordering to <i>all</i> players. The first case creates confusion and arguments, as well as feelings of distrust directed towards the chat software. The second case <i>might</i> cause a vague sense of displeasure at the quarter-second delay.<p>&gt; Maybe the best way to claim top lane shouldn&#x27;t be the first person to type &quot;top&quot; and hit enter.<p>Agreed. Perhaps people could be civil when they play their games. :)<p>[0] In this case, RTT doesn&#x27;t matter. Only the time required to get a packet from you to the server matters. I think that we can <i>reasonably</i> assume that the worst case RTT from anyone who&#x27;s playing a vaguely-latency-sensitive online video game to anywhere else on the Internet is 500ms.<p>[1]  Honestly, it <i>might</i> take <i>half</i> of this time for the pixel issued by a draw command to your graphics card to appear on screen.
