Ultimately whether or not you hit another player, depends on the server. If the server is running crazy slow due to a high player count, you will have to hit the player at the position he is at, during one of the servers update loops. So technically for you, if the server is running crazy slow, even though for 0,2 seconds, the player appears to be moving on your screen. The player may technically be standing still on the server. That means that in order to hit the player, you will need to hit him at the point he is currently at, or more likely, the point he is at during the next update loop of the server. But with that said, we recently discovered a way to dramatically improve the performance of the server which makes a slow updating server less likely, though we are still to see what exactly happens when theres 80 players on a server with this new improvement.
