It definitely varies a lot in the US. There are benefits to being curious and playing around with things vs just believing every factoid you here. The article discusses some of the various configs and rules pretty well. After reading about the distance requirements, it's unsurprising to me that smaller apartment buildings or lobbies are where I've most frequently seen "more responsive" door close buttons. It was pretty damn quick in my old apartment, probably tiny lobby + not super fast door opening so the minimum was eaten into by the time from "ding" to "fully open." I used to see people visibly surprised that it worked when I used it in that building! ("Push to cross" buttons have the same sort of fun, but with slightly more potential consequence for the people who seem to refuse to ever push them...)
