I'm calling BS on this.
I plugged in my own stats and according to this there are only 80 men in the US who meet that. I put in my last girlfriend's and there's supposedly only 38 women like that in the US. Yeah, no.
This is meant to capture a universe of people who you'd be willing to date, not the stats of a specific individual. There's literally one person who matches my specific stats in this calculator (and literally none pre-transition, so it's not being thrown off by that); it's can't capture individuals.
It clearly does not pass the sniff test. Just isolate one or two filters and you see nothing makes sense - for example, it estimates only 1% of women are gay and that a majority of women aged 19-25 have children, when the median age for women having their first child is 30. And yes, if a "tool" with a few generic filters can isolate a country of 300m+ people down to a single person, or even 80 people, it is completely useless.
