At about 120 ms, it becomes apparent that most of these clicks are the result of clicking too soon, and just getting lucky. Otherwise, you might see a smoother ramp from 0 to 130, but it seems to just be noise.
The cutoff for leaderboard scores used to be 130, but some of the fastest 99.9 percentile of players on the site complained, pointing out how often they got legitimate scores in that range. Now it's 100 ms.
So while I agree, I'm still saying it's like a 97% skill 3% traits. Nothing at all worth writing home about. Eat your wheaties, practice micro and quit your day job. BAM! Now you have a better chance to become a pro than 99% of the people playing SC2.
Not disagreeing with that skill trumps traits by a large margin, just pointing out that reaction time doesn't fall solely in the realm of "born with it."
Perfect DNA from on high means jack if you don't know how to play.
I agree that the bulk of skill is trained, but I don't think these results can be extended to SC2.
This test is largely about a feedback control loop: how fast can a person respond to the test. SC2 is nowhere near about responding - the best example off the top of my head would be a person noticing and responding to a Drop Ship in their base.
SC2 is all about prediction and knowing your next move; that is a feed forward loop. When the person in his mind has 'These are my next 5 actions' , they can executed much faster than if their brain was serially fed each action one at a time without knowledge of the next action.
To be fair, even that test isn't purely about response time: the more you play, the faster you can get as you 'prepare yourself' to better respond to the transition.
That is almost CERTAINLY the result with people who have ~100ms response times because the ACTION POTENTIAL (the electrical signal from your hand to your brain) alone takes ~40ms to travel in one direction. That doesn't include the time that your brain takes to process what it sees, send ANOTHER action potential back, and then contract your muscle. But if a person can time it will with a little bit of luck, they can initiate that action before the message actually appears to result in a faster time.
Edit:
This entire topic is definitely a tagent to the topic, but I'm not convinced that clicking a mouse 100ms faster than another person, over the course of a 20-30 minute game, is going to represent anything meaningful.
A lot of clicks in battle that doesn't effectively move your marines out of the path of high templars means nothing. You need to respond to it for sure, but a 50ms advantage isn't going to mean much especially given the lag with internet play.
Being able to mentally process parallel events, respond to them, and initiate your own actions is what matters the most...and that can also be trained.
