Supercharge.info gets its information from sources such as this forum, or other discussion forums - so don't take it as some type of official designation. It's sort of a group-info site sort of like group funding. It's a highly useful sight and I've been using it since 2013 where there were like 17 superchargers, its just not official, nor do they have any more insight than anyone else. They just collect the information that locals and others present to them through things like forums and facebook pages. Occasionally, that info is a tad early - such was the case here. But I love the info they provide. I'm kind of addicted to it (I don't want you to think I am disparaging the site, because I am not in anyway).
