After much testing I finally understand exactly what 'time nudge' is and what exactly it does. It's the key to manipulating the lag compensation algorithm and is what causes some players to have a faster reaction time than others.

'Time Nudge' is the interpolation buffer for player movement. I recently figured out there's a server-side buffer as well as a client-side buffer. Previously I was only aware of the client-side buffer.

Manipulating the server-side buffer is the key to giving yourself a reaction time advantage over other players in the server. You do this by causing the UDP packets you're sending to the server to be out-of-order.

Since packets the server is receiving from you are out-of-order, the server has to increase it's 'time nudge' buffer so it can buffer multiple UDP packets in order to rearrange the packets into the right order.

Naturally this causes the server to delay processing your packets which in turn causes the server to delay sending updates about your player movement to everyone else. This is why some players seems to always see you first and react faster.

What's the easiest way to increase server-side 'time nudge'? Playing on wifi is the easiest way, because wifi causes your ping time to fluctuate which causes packets to reach the server out-of-order instead of in-order.

Q: What connection type do most console players play on?

A: Wifi

 

So this explains why console players seem to have an advantage over PC players who are using wired ethernet. It's actually a disadvantage to have a completely stable connection.
