Not sure I understand the information at your link, but as far as I can tell, the most weight that has been deadlifted by a teenage female (<20yo, open weight) is 391lbs.
Maybe I suck at web search? Is there a teenage female record holder who has smashed that weight and I’m just not finding anything about it?
If you don’t think this is possible, you know nothing about highschool athletics. http://usapl.liftingdatabase.com/records-default?priority=10...
Teen girls can actually pull quite a lot heavier than 405, ha.
