It is gonna be a totally experimental feedback, but nonetheless it may help you relating to the importance of fast feedback latency ; the best stays to experience it yourself.

I noticed during my thesis on realtime systems that my brain had difficulties compensating for latency, even more for jitter (inconsistent latency). I do more typos when I have a high latency. I notice it when playing music in a high latency context, or when the ssh connection has a high ping. We did the experiment slowing down the click of the mouse by 100ms. Users hated the results.

I'm also more productive if I can notice my typos 100ms earlier, or confirm that everything I previously typed is good earlier. Even if it takes me 500ms to process the information displayed on screen, it stays on the critical path of the overall task speed performance.
