I'm just guessing but this chaff sounds like it wouldn't actually change the latency or delivery of your actual keystrokes while buffering or jitter would. So the "real" keystrokes are 100% the same but the fake ones which are never seen except as network packets are what is randomized. It's actually really clever.
