I was surprised, too, and looked it up. WCA officially doesn't differentiate. The human World Record is 3.51 currently held by a Yiheng Wang (male). So there is quite a gap to the new record by Lian Yunzh. But if she continues like that, I think we will find out soon whether there are any biologic reasons for the gap or if it is just because there are many more males into that kind of thing.
