Similar experience here: I started early and played the game for a while, and years later with very little activity I'm still top 0.08%. My technique was to focus on speed. I wrote a tool to alert me to new questions and would often answer within one to two minutes. This wasn't as disruptive as it may sound to my real work, as I knew my domain well enough, so it was the mental equivalent of getting up for a quick walk.
